. In mice, the following alleles were used in a cross: W = waltzing gait w = nonwaltzing gait G = normal gray color g = albino B = bent tail b = straight tail A waltzing gray bent-tailed mouse is crossed with a nonwaltzing albino straight-tailed mouse and, over several years, the following progeny totals are obtained: waltzing gray bent 18 waltzing albino bent 21 nonwaltzing gray straight 19 nonwaltzing albino straight 22 waltzing gray straight 4 waltzing albino straight 5 nonwaltzing gray bent 5 nonwaltzing albino bent 6 Total 100 a. What were the genotypes of the two parental mice in the cross? b. Draw the chromosomes of the parents.c. If you deduced linkage, state the map unit value or values and show how they were obtained.
