Question

In fruit flies, a dominant gene, G, codes for the trait of gray body color. A recessive gene, g. codes for black body color. Two fruit flies mate to
produce offspring
GG
Gg
Offspring
Which prediction about the offspring's body color is based on the properties of genetic reproduction?
O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.

Answer 1

Correct answer - The offspring can only express the trait of gray body color.

Why? - As we set the punnet square. We get the results, (2)GG and (2)Gg. GG = Gray and Gg = Gray.
