Subject: RE: MC.Personalities. Cyber, & in the flesh.
Guest - firstly, are you sure about that figure of only 30 genes which differ amongst humans? I ask because I know of several single gene disorders, and scientists are always talking about different genes which affect our likelihood of having different diseases (such as breast cancer, schizophrenia, etc). And I'm sure I have heard of more than 30 different instances.

Anyway, even if it were true - 30 different genes add up to a hell of a lot of variation. Say on average there were only 2 alleles for each gene - that makes 2 to the power of 30 (which I make over 1000 million combinations). Also, genotype does not equal phenotype. Genes and environment interact to produce all our characteristics. So in short, every human is unique.

So next time you want to hijack the conversation, make sure you choose a subject you actually know something about.....
