In dormice, a multiple allele series at an autosomal locus is responsible for ear shape: Round (ER) and square (E5) alleles are incompletely dominant over each other resulting in an oval ear shape. Round and square are both dominant to triangle (E) and lobe (E); 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: in relmuise, is 'n veelvoudige allele-reeks by 'n outosomale fokus verantwoordelik vir die oorvorm: Ronde (E) en vierkantige (E) allele is onvolledig dominant teenoor mekaar, wat 'n ovaal oorvorm tot gevolg het. Rond en vierkantig is albel dominant teenoor driehoekig (E) en gelob (E); en driehoekig is dominant oor gelob. Terwyl hy 'n veldopname doen, merk 'n dierkundige die volgende aantal relmuise op met betrekking tot oorvorm Round | Rond: 105 78 Square | Reghoekig: Oval | Ovaal: 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: Gestel die populasie van relmule is in Hardy-Weinberg-ewewig vir hierdie lokus, skat die alleelfrekwensies vir elk van die allele (round to three decimals) (rond tot drie desimale) Question 2 Complete Marked out of 1.0 Fr(ER)=p= Answer: 0.331 Question 3 Complete Marked out of 1.0 Fr(ES) = q = Answer: 0.273 Question 4 Complete Marked out of 1.0 Fr(ET) =r= Answer: 0.154 Question 5 Complete Marked out of 1.0 Fr(E) = s = Answer: 0.291 Question 6 Complete Marked out of 2.0 What percentage of round eared dormice do you expect to be homozygous? (round to the nearest whole number) Watter persentasie van die ronde oor relmuise verwag jy sal homosigoties wees? (rond tot die naaste heel getal) Answer: 13 Question 7 Complete Marked out of 2.0 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) As witvlek 'n resessiewe X-gekoppelde fenotipe is en 40% van die mannetjies het wit kolle, watter persentasie reimuise kan verwag word om ovaal ore EN wit kolle te h? (Neem aan dat hierdie lokus in Hardy-Weinberg ewewig is, die geslagsverhoudings gelyk is, en dat die loki onafhanklik sorteer) (rond tot die naaste heel getal) Answer: 7 In dormice, a multiple allele series at an autosomal locus is responsible for ear shape: Round (ER) and square (E5) alleles are incompletely dominant over each other resulting in an oval ear shape.
