You have identified a new species of Drosophila with
large wings and long legs on a trip to the Amazon Basin. The w+
(large wings) is completely dominant over w (small wings). The l+
(long legs) is completely dominant over l (short legs). You cross
true breeding males with large wings and long legs to females
heterozygous at both the w and s loci and you observe the following
progeny when 1000 males and 1000 females were counted:

males:
Large wings short legs 420

Small wings long legs 380

Large wings long legs 110

Small wings short legs 90

females:
Large wings short legs 0

Small wings long legs 0

Large wings long legs 1000

Small wings short legs 0

(a) are these genes linked?
(b) what are the parental and recombinant types?
(c) list all 5 genotypes represented for males and females above
(ignore 0 classes). (d) Calculate the distance between these
genes?
