State what are the reciprocal classes for the male progeny

Reference no: EM13177102

Three genes on the Drosophila X chromosome are w (white eyes), f (fringed bristles and t (ticklish - a behavioral mutation). All three mutations are recessive. The following numbers of male progeny were obtained from a test cross between a heterozygous female and a wild type male.

Wild type: 169
Ticklish: 19
White: 8
Fringed: 304
Ticklish white: 301
Fringed white: 21
Fringed ticklish: 6
White fringed ticklish: 172
Total: 1000

a. What would you predict would have been the phenotypes of the female progeny of the cross?

b. What are the reciprocal classes for the male progeny?

c. What was the arrangement of the genes on the chromosomes in the heterozygous female?

d. What are the map distances between the genes?

e. Calculate the interference value for the double crossovers.
