Question

For a particular trait, Gg, what is the probability of two heterozygous parents producing an offspring with the genotype GG?

Answer 1

The probability of producing an offspring with GG is 25% or 1/4 because the cross between the parents Gg and Gg will produce GG, Gg, Gg, and gg

Answer 2

The probability is 25%.

The genotype is how to note a gene, an allele, a genotype. While the phenotype is an observable characteristic of an individual resulting from the interaction of the medium in which he lives and his genome.

When we cross two heterozygotes (Gg with Gg) it gives us: GG, Gg, Gg and gg.

So in terms of probability, we will have the following genotypes:

25% dominant homozygous GG

25% gg homozygous recessive

50% Gg heterozygote
