Allele frequency??

So...nothing major happened today. I learned an equation in bio (that actually isn't much of an equation in the sense that most math people would think of it). It goes p^2+2pq+q^2 = 1

So basically, that equation simplifies down to (p+q)^2=1 ? That makes sense -_-;

That stuff makes me happy :) Even though I have little clue what's going on with alleles...(they mention them on CSI:, but that's about it -_-)

Yeah.

Alleles are simple; for every trait there are two (or more, in some cases) possibilities. Usually one is recessive (meaning you have to have two recessive alleles for it to be expressed in you) and the other dominant (meaning if you have one dominant and one recessive only the dominant is expressed).

Genetically speaking it boils down to the fact that chromsomes come in pairs, with one allele on each chromsome in the pair. If you have a dominant allele in one of the chromosomes in the pair and a recessive in the other, you're heterozygous and will have the dominant version of the trait expressed.

I hope that made sense. I know you haven't taken bio yet, so I tried to keep the most confusing bits out of it. ^^;
