Assume that D, E, F, G, H, and I are autosomal genes on different chromosomes. From the mating
(parent A) Dd ee Ff GG Hh li x
(parent B) Dd EE FF Gg Hh ii.
A. What is the probability that one of the offspring will have the genotype Dd Ee FF Gg hh li?
B. What is the probability that one of the offspring will be heterozygous for each allele?
You believe that the gene you're investigating, eyes absent, is an autosomal recessive mutant allele F7 ge in Drosophila. You set up a cross between a true-breeding mutant male and a true-breeding wildtype female to obtain the F1 generation. You then cross the F1 flies. In the F2 offspring, you observe the following:
237 wild-type males
180 wild-type females
70 mutant males
83 mutant females
Based on these findings, is the mutant allele autosomal recessive? How do you know?
Three genes in fruit flies affect a particular
trait, and at least one dominant allele of each
gene is necessary to get a wild-type phenotype.
a. What phenotypic ratio would you predict
among the progeny if you crossed triply
heterozygous flies?
b. You cross a particular wild-type male in
succession with three tester strains. In the
cross with one tester strain (AA bb cc), only
1/4 of the progeny are wild type. In the
crosses involving the other two tester strains
(aa BB cc and aa bb CC), half of the progeny
are wild type. What is the genotype of the
wild-type male?
