Question

in peas, the allele for green seeds (g) is recessive to the allele for yellow seeds (g). a homozygous, green - seeded plant is crossed with a homozygous, yellow - seeded plant. what will be the expected genotype(s) of the offspring?
all gg
all gg
50% gg and 50% gg
50% gg and 50% gg

Explanation:

Step1: Determine parental genotypes

A homozygous green - seeded plant has genotype \(gg\). A homozygous yellow - seeded plant has genotype \(GG\).

Step2: Use Punnett square or gamete combination

The green - seeded plant (\(gg\)) can only produce \(g\) gametes. The yellow - seeded plant (\(GG\)) can only produce \(G\) gametes. When \(g\) (from green - seeded parent) combines with \(G\) (from yellow - seeded parent), the offspring genotype is \(Gg\) for all offspring.

Answer:

all \(Gg\)
