Question

Two parents who are both Gg for a gene are crossed.

What is the genetic makeup of the offspring?
Question 4 options:


some GG, some Gg, some gg


all either GG or gg


all GG


all gg

Answer 1

The answer is A you would get 25% GG 50% Gg and 25% gg so you would get some of all of the above.

Hope this helps you :)

Answer 2

The unit of inheritance is called gene it passes traits from parents to the progenies. Heterozygous Gg and purebred GG and gg will be the genetic makeup.

What is Punnett square for the cross?

Punnett square is a cross of the parent generation and the representation of the progenies in a squared box.

The genetic alleles of the parent are heterozygous for the trait and are shown as Gg.

Check the image attached below for the cross.

From the cross, it can be said that when parents having heterozygous traits are crossed then the offsprings produced have the following phenotypes and genotypes:

• Phenotype = 3 : 1
• Genotype = 1 : 2 : 1

Therefore, option A. some GG, some Gg, some gg will be the genetic makeup of the offspring.
