Hmm It is kinda hard to believe that, when you can look at a stork and vulture and analyze their physical characteristics, a person would most likely say "hey that new world vulture has got to be more closely related to an old world vulture than a stork." just by looking at them. But going...

"I felt slightly concerned that someone on a biology page would confuse socially constructed gender with biological sex."

Who is that directed to?

Re: EVOLUTION; what influences allele frequency to change?

ok I just skimmed over your stuff, I am really busy studying for two chem finals tomorrow. ok rr frequency is zero, and r frequency is .075. This is because the genotype frequency (rr) has been fixed not the allele (r)frequency. individuals with allele combination (genotype) of rr have been trimmed ...

For the last question we see that the genotype rr is approaching a frequency of zero, once it reaches zero this means there is a fixation in the population. The population has now evolved and the rr individuals have been trimmed off the population. As for random mating - no, the allele frequencies w...

Interesting ideas. But how can you say with such certainty? Got any sources I can scope out? Really interesting by the way, I never thought about pheromones.

ps - dig the hair.

"but your ideas are interesting when there has been zero observations before recent years that mintion homosexuality in the animal kingdom."

We are in the animal kingdom F.Y.I.

Group your questions to make it easier for me to understand what exactly you want. Genetic drift = when alleles are lost in the gene pool and yes it changes the allele frequency. H-W principle shows what would happen if mating was random and no evolution factors were in play (ex natural selection, g...

Re: Homosexuality - mutation? Evolutionary reasons.

Ok. Homosexual behaviour in this context = doing sexual things with the same sex (i.e. sex). You should know this.
