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?
Answer (3)
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.
The genotypic ratio of the offspring from a heterozygous gray female (Gg) and an ebony male (gg) is 1:1, resulting in one gray-bodied genotype (Gg) and one ebony-bodied genotype (gg).
