Problem:
Imagine that this company sells polka-dotted bears and striped bears (as shown in the picture). Polka-dotted bears are slightly more popular, so the population is 58% polka-dotted and 42% striped. Each type of bear is homozygotic - polka-dotted bears are PP and striped bears are SS. When they are crossed, the heterozygote (PS) is polka-dotted with stripes.
Required:
Question 1: Assuming Hardy-Weinberg Equilibrium and random mating, what will the allele frequencies be in the next generation (in the F1 generation)?
Question 2: What will the genotype frequencies be (in the F1generation)?
Question 3: now assume that people think the heterozygote is funny-looking and do not breed it. (But assume random mating between the other two types.) What happens to the allele and genotype frequencies in the next generation (this is now the F2generation)?
Question 4: Starting again with the F1generation (whose allele and genotype frequencies you calculated in a & b), now assume that people like one type more than the others, so if they have two, they always have two of the same. Assume also that some people like the heterozygote, so all three types get bred. How does this change the allele and genotype frequencies in the F2generation?
