stellarik [79]

Answer:

Genotype of long winged fly is Ll

Genotype of short winged fly is ll

Explanation:

Given

Allele for long wing trait is "L"

Allele for short wing trait is "l"

When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 1:1

Let us say that the genotype of long winged fly is Ll

and the genotype of short winged fly is ll

The cross between the two will produce following offspring

Ll * ll

Ll, Ll, ll, ll

Out of four off spring two have long wings (Ll)

and the other two have short wings (ll)

Thus the ration of long to short wing offspring is 2:2 i.e 1:1
