Yh It was one of the hardest HW questions I've done before. I took a lot of time to understand it but basically the Second horse had 2 genotypes which made the questions very awkward.

Would’ve been 9/900=0.01 and then square root it to find the other numbers

Do you think for the next part of the question they would’ve accepted selection pressures and migration as reasons why not in equilibrium?

idk i actually drew the equilibrium sign in chemistry somewhere at the question paper when i was figuring out wtf is going on then i wrote some bs like the semi-desert conditions might not be the optimal conditions for horses to survive
