Chromatophores WOW!
Ally:
Diploidy: Diploid nature of two eukaryotes hides recessive alleles, keeping them in the gene pool; if the frequency is rare, there is asmall chance that heterozygotes will mate to produce a recessive homozygote.
Balanced polymorphism: Natural selection maintains stable frequencies of two or more phenotypes.
- Heterozygote advantage: Heterozygotes may have an advantage over homozygous individuals. Carriers of the sickle-cell disease, for example, have a greater resistance to malara.
- Frequency-dependent selection: Advantage of a morph declines when the morph becomes too frequent in the population. Allows for balance between frequencies of more than one morph.
Neutral variation: Some traits may not have affects on reproductive success (some argue that there is no such thing as neutral variation, just effects of genotype are less obvious in certain environments).
Pleiotropy: Genes have more than one phenotypic event. Even if some part of the expression is harmful, if another part if beneficial, the gene can be preserved in the population.

Well young lady, you certainly are lucky that didn't come up on your test.
Ally:
There actually just shouldn't be a "two." ANYWAYS LOOK AT THE DISCLAIMER
and chromatophores
jhocking:
Yours might change, but mine look cooler.

I know a little from this because I happen to be a reptile hobbyist who is interested in the breeding of cornsnakes and ball pythons, both of wich have many different genetic color morphs to to cross-breeding. Of course I barely understand it at all and really I just wanted to post some links to cool pictures of snakes:

and who did we say was prettier than who?
Edit: oh and this was acool animated chart
