Problem set 1 9/7/07 1)a) Assuming that both the allele for normal wings and body color are dominant to the mutant alleles, the phenotypic ratio in the F2 generation would be 9:3:3:1; 9/16 of the individuals would be brown with normal wings, 3/16 would be brown with curved wings, 3/16 would be ebony with normal wings, and the last 1/16 would be ebony with curved wings. b) Assuming that the ebony body and curved wings only occur when the individual is homozygous for the gene, the probability of any individual being male and homozygous recessive for both genes is 1/2 x 1/16= 1/32. The probability of three such individuals is 1/32 x 1/32 x 1/32=1/32768. c) Again assuming that the e + gene is dominant to the e gene and that curved wings only occur with the homozygous c combination, the probability of any one individual being female and brown with curved wings is 1/2 x 3/16=3/32. The probability of three such individuals is 3/32 x 3/32 x 3/32= 9/32768. 2)a)
