In dormice, a multiple allele series at an autosomal locus is responsible for ear shape: Round (ER) and square (ES) alleles are incompletely dominant over each other resulting in an oval ear shape. Round and square are both dominant to triangle (ET) and lobe (EL); and triangle is dominant over lobe ears. Whilst doing a field survey, a zoologist notes the following numbers of dormice with regards to ear shape: 105 Round | Rond: Square | Reghoekig: Oval | Ovaal: 78 64 Triangle | Driehoekig: 35 Lobed | Gelob: 26 Assuming the population of dormice is in Hardy-Weinberg equilibrium for this locus, estimate the allele frequencies for each of the alleles: Fr(ER) = p = Fr(ES) = q = Fr(ET) =r= Fr(EL)=s=
| Fr(ER) = p = Fr(ES) = q = Fr(ET) =r= Fr(E¹) = s = What percentage of round eared dormice do you expect to be homozygous? (round to the nearest whole number) If white spotting is a recessive X-linked phenotype and 40% of males have white spots, what percentage of dormice could be expected to have oval ears AND white spots? (Assuming this locus is in Hardy-Weinberg equilibrium, the sex ratios are equal, and the loci assort independently.) (round to the nearest whole number)
