Let me try this again: Increasing the frequency of recessive alleles. A biology...

...question.? OK, I'm supposed to devise two different scenarios that will increase the frequency of the recessive allele: one should be for a homozygous condition, the other for a heterozygous condition.

I know that natural selection and the bottleneck effect/genetic drift will come into play, but I don't get how they could effect genotypes that are homozygous or heterozygous differently...I am confused!
