comment Question about Autosomal Recessive Alleles
I would also add "human error" to the list, a person changing the outcome, e.g. by contaminating the sample or a spelling error while transcribing the result. This might be surprisingly likely - somebody overly tired, or having a bad day.

comment How many people are required to maintain genetic diversity?
It's just mathematics. If you pick two outbred mice/rats etc. and mate them, the offspring is about 0,5-1% more inbred than their parents (meaning both their copies of any gene are a tiny bit more likely to be inherited from one ancestor mouse). If you have enough animals, this effect is smaller than the effect of other phenomena, such as genetic drift (compare with the assumptions behind Hardy-Weinberg equilibrium). I don't know the exact equasions behind those numbers, I just know, that this was calculated and such-and-such numbers are used.

comment Do spouses begin to share genes over time?
I get that this is a legit question, but you are so sexist in formulating it I hope you never write again.

comment Botulinum Toxin
Yes, I doubt that. I think there might be very old studies showing the principle - how it was discovered, or studies pinpointing the exact curve in order to formulate those recommendations that I quoted.

comment Hardy-Weinberg applied to three alleles and stimation of allele frequencies
So you omitted some data of this question? The thing is, you can substitute whatever you want, e.g. 1-p=q+r or p=1-q-r, but that leads you nowhere if you don't have any more data. Something like p^2+q^2+r^2=3pq+3pr+3rq is crucial to solving this problem. Anyway - these are two equasions, you still need a third to ba able to assign specific numbers to p, q and r.

Why do you need to separate homozygotes from heterozygotes?

comment Two brown-haired people have two children, P and Q. P has blond hair. Q has brown hair. What is the probability that Q is heterozygous?
Then you have one more argument: this was probably a high school homework, so it has to use what kids learn about Mendelian heredity, not something deeper and more elaborate.

comment What prevents a pregnant woman's immune system from recognizing her fetus as nonself (and attacking)?
Right now I don't remember the full story, but part of it is that pregnant women are somewhat immunosupressed and there is something like a layer of NK cells around the placenta making sure nothing attacks it. Not very practical to adapt to organ transplants.
