In fruit flies, the gray body color
(G) is dominant to the ebony body
color (g). What is the genotypic
ratio of the offspring of a
heterozygous gray female and an
ebony male?

Sagot :

50% gray 50% ebony genotype a are as follows: Gg, Gg, gg, and gg

Answer:

The correct answer would be 1 (Gg) : 1 (gg).

The genotype of a heterozygous gray female would be Gg.

It will produce two types of gametes G and g.

The genotype of an ebony male would be homozygous gg as ebony is a recessive trait.

It will produce only one type of gamete that is, g.

The cross would produce offspring with the two types of genotype Gg and gg in the ratio 1:1.
