A sample of 500 field mice contains 225 individuals that are D1D1, 175 that...

part A you just take the 265 d1 mice and half of the 155 d1d2 mice add those numbers together divide by total theres the frequency.
b do the same way but for d2
c if it is then the frequency for each genotype (for d1 this is d1d1 so you take your d1 frequency and square it then multiply that by 500 if its in equilibrium you should get the same number of d1d1 mice as before (265) bc this means they aren't evolving.
I need help with D, im not sure if it could have anything to do with inbreeding the book doesn't say much about this.. it just says it can increase homozygous genotypes

got irritated and guessed that it wasn't responsible as if you do the expected number of D1D1 and D2D2 they are both declining... that was wrong. apparently it IS a possible explanation. thanks mastering genetics for teaching me so well.. it makes no sense to me but that's the answer. Any ideas why inbreeding would be a possible explanation?
