Unformatted text preview: + cv + v f cv If any results do not match expectation (reject null hypothesis), offer possible explanations for why this might happen Mendel’s law of segregation => two alleles separate into different gametes in equal proportions Expect: ½ gametes (offspring) to possess the wild-type allele; ½ to possess the mutant allele So for v: Ho: The expected segregation ratio of the two alleles for the eye color gene is 1 wild-type (v + ) : 1 vermillion (v)...
