- The A and B genes are found on the same chromosome, with dominant (A, B) and recessive (a,b) alleles. After crossing AaBb x aabb, 90% of the offspring are have AB or ab phenotypes, 5% are Ab and 5% are aB. Q1: Which alleles were linked on the two parental, non-recombinant chromosomes in the AaBb parent? AB and abQ2: How many cM (map units) separate the A and B genes on the chromosome? 50
- You have sampled a population of toads over three years for the BrrP locus. The first year, you calculated these allele frequencies: B = 0.75 and b = 0.25. The second year, you determined that B = 0.66 and b = 0.34. What can you conclude from these data?a. This toad population is not in Hardy-Weinberg equilibrium and not all of the assumptions of the Hardy-Weinberg law are valid for it.b. This toad population is in Hardy-Weinberg equilibrium and not all of the assumptions of the Hardy-Weinberg law are valid for it.c. This toad population is in Hardy-Weinberg equilibrium and all of the assumptions of the Hardy-Weinberg law are valid for it.d. This toad population is not in Hardy-Weinberg equilibrium and all of the assumptions of the Hardy-Weinberg law are valid for it.
