Genes are the instructions found in each cell of the body that determine how the body is to develop and function. Genes are strung together, one after the other, and packaged into individual chromosomes, which are transmitted from parent to child in a very regular fashion. All chromosomes come in pairs; in humans, there are 23 pairs in all. One chromosome from each pair is inherited from the mother, and one from the father. A gene that codes for a particular function may come in several different forms; that is, a gene that controls pigment in hair may code for blonde hair or black hair. The two genes in a pair may not agree. If the code for one gene is expressed no matter what the other gene says, the first gene is said to be dominant. If both of the genes have to be the same in order for that code to be expressed, those genes are said to be recessive. The commonly used example is that a person with one gene for black hair would have black hair, whether or not the other gene was for blonde hair. Blond hair would show up only if both of the genes in the pair were for blond hair. This is an oversimplification of the genetics of hair color, but it does illustrate the basic definition of dominant and recessive. Now with that in mind, pink haired girls in anime are considered to be redheads since that is the chroma of hair that is the closest parralel in real life. Red hair is not actually a recessive gene (like blonde is), but is rather an "incomplete dominant." In the world of genes, there are dominant genes, which take over any recessive gene (brown, black), recessive genes (blonde), which will be taken over by any dominant gene, or incomplete dominent genes (red). Incomplete dominant genes will "blend" with any dominant, recessive or other incomplete dominant gene. So you've got yourself a red headed parent (let's call those genes aa) and a blonde parent, which we'll represent as bb. 100% of the offspring will have one hair color gene from each parent, or ab. This means red and blonde. Since red will always blend with other genes, the resulting hair color should be a blend of blonde and red, or strawberry blonde. In the case of my parents, which both have brown hair (let's call the brown/black genes C), either one parent or possibly both are carrying one "a" in addition to their brown or black genes, with the possibility of even a blonde thrown in (CC, Cb, or Ca) With this in mind Mamoru is probably a Ca[/b] and Usagi an bb. VMoomooV\>Usagi> | b | b | C | Cb | Cb | a | ab | ab |

...Ok, that makes it a little complicated...
Let's just go with my theory ok?
Queen Selenity had VERY pale pinkish hair, it skipped a generation and hit ChibiUsa with full force.
There ya go. ^_^

Ok those are both good theorys but heres mine... The person who made Sailor Moon wanted her to have pink hair so they drew it pink!!! lol

But if a person has brownish hair and wants to have a kid with pink hair, what color of hair would the other person's be? ;D It depends on if there is a history of red hair in the brown haired person's family. if there is not then the strongest bet would be a person with pink or purple hair. and if we are talking anime genetics its even more complicated. I'd have to do more research.

Hmm... I have friends who, the mother has flaming red hair, and the father has black hair... and all of their kids have platinum blond hair.
So, it's just a switcheroo...
blonde + black = red/pink red + black = blond red +blond = black? <- dunno about this one.

My theory on the pink hair: they still had some pink paint left, and didn't know where to put it.
The genes theory is pretty much impossible, trying to create the possibility of a blonde anime character mating with a darkhaired anime character to spawn a pinkhaired anime character, by confusing the reader with microbiochemiphysical terms such as 'genetics', 'dominant' and 'parent'.
The pale pinkish hair theory is highly unlikely, given the fact that Usagi really does have sunshine blonde hair. Pale pinkish hair would give a whitish look, not a yellowish, and certainly not as yellowish as Usagi's. Other than that, pink hair purposely skipping a generation on its own is generally impossible in anime series, as well as in real life.
Now, the person who drew Sailor Moon would most likely want the daughter of the princess to be a beautiful blonde, and not a highly annoying, pinkhaired little brat that comes back from the future to ruin Usagi's life even before she officially enters it.

Gah ... no offense everyone, it's late 'n before I knew it, this was up.

The funny thing is that it happens in real life where a person with blonde hair and a person with black hair produce redheaded offspring. So no, it is not impossible because it happens exactlly as I've explained it.

Gomen nasai for the word 'impossible', it's quite a strong definition. And if it does happen, I'm gonna find myself a blonde bride and fertilise her and have her give birth to a beautiful sugar-pink-haired girl. That'd be somethin.

It'd only work if you were a carrier for the redhaired gene(like me) it might show up as sugar pink very early on (like my sister) before it fades in to either blonde or red depending on how long the strength of the red haired gene last. But still, "highly unlikely" is still too much. Since the way I described it is the way red hair works in the real world. and saying either impossible or highly unlikely is like saying that having redhair is impossible or highly unlikely. I've known alot of red haired people.

No, highly unlikely is not too much, since it's quite rare to have redhaired children from a blonde parent and a darkhaired parent. It's much more likely to have redhaired kids when either of the parents have red hair already.

No, highly unlikely is not too much, since it's quite rare to have redhaired children from a blonde parent and a darkhaired parent. It's much more likely to have redhaired kids when either of the parents have red hair already. Did you even read how the top one works or did you just skip it when it said genes because it required too much thought on your part? Rife (1967) concluded that the proportion of red-haired offspring in families in which one or both parents are red-haired is too high to support the hypothesis that red hair is inherited as a simple recessive. The family data and gene frequency analysis suggested to him that the presence of red pigment in the hair is dominant to its absence and is hypostatic to brown or black. Which means that, as I said before, red hair is not a recessive gene (like blonde is), but is rather an "incomplete dominant." Seceral years ago scientists discovered that the melanocortin 1 receptor, a protein encoded by a gene previously discovered in mice, was responsible for the production of red hair in humans. Everybody has two copies of this gene but there are slight changes in the gene that are very common in European populations. If you have one of about four or five common changes in this gene and, one of these changes are found on both of your chromosomes, then you are likely to have red hair. A little bit of basic genetics: you have two copies of every gene, you inherit one from your mother and one from your father. If both of these genes are different, with respect to the changes that might lead to red hair, then you will have red hair. If however you only have one change, you have an increased chance of having red hair but, the chances are that you won't have red hair, although you will tend to be more sun sensitive than the average person. Such a type of inheritance is close to what geneticists describe as an autosomal recessive mode of inheritance. This means, in practice, that both your parents may not have red hair, but both could be carriers for the gene for red hair. If this was the case, perhaps one in four of children might have red hair. If one of the parents has bright red hair, and therefore carries two of the changes (one on each of their chromosomes), and the other parent is a carrier, then perhaps 50% of the children might have red hair. It is this aspect of the inheritance of red hair that tends to lead to the various permutations of the milkman joke. There are different sorts of red hair. Some people seem to have what we call gstrawberry blondeh, some bright red and some auburn. As far as we know, the genetics underlying these differences are fairly similar, in that changes in the gene referred to above, seem to be important for all sorts of red hair. However, if you have bright red hair it seems you are much more likely to carry two different copies of the gene than if you are a strawberry blonde. There are some other puzzles about red hair. Some men might have red beards but dark coloured hair. This is not entirely surprising as in many mammals the front of the body is a slightly different colour to the back. In some animals, the molecular basis of this is clearly understood, as in these animals, they produce a different protein that seems to have the opposite effects to the red hair gene mentioned above. In man, we don't think this is the case, but we also observed that people who do have red beards are more likely to carry at least one different copy of the red hair gene. Another puzzle is why hair colour changes so much during life. Most people are aware that hair colour tends to be lighter at birth and gets darker, particularly during adolescence and puberty. Apart from saying that the cells that produce melanin become more active at this period we don't understand why this is. Similarly, of course, we don't really understand greying and lightening of the hair in old age. People with red hair often have different coloured hair at different times of their life. It seems that it is more likely to be red in childhood or in early adult life, than in later life. Basically everyone carries the RHC(melanocortin 1 receptor) so even if your parents DON'T have red hair there was a 25% chance that you would have had red hair. And a 25% chance is not "Highly unlikely".

I forgot to mention.
My sister has red hair. I have reddish brown hair. My mother has blonde hair. My father has black hair.
Now what was that about highly unlikely?

I know you're both trying to prove a point here, and kudos to you on that... but... dudes... come on... it's a cartoon... ChibiUsa is a cartoon character or a drawing (depends on Manga or Anime...) Who cares? LOL! Explain Michiru's greeny blue coloured hair... has she dyed it perhaps? Or Setsuna, with the green streaks... same deal? It's not that huge, really... it's just the way the artists have done it... whether it's the way the creator intended or not, it's been done, so... does it really matter why she has pink hair?
