Question

in pea plants, green pea color (g) is dominant to yellow pea color (g). cross a homozygous green pea plant with a yellow pea plant. what is the genotype ratio of the offspring?
○ 1 gg: 2 gg: 1 gg
○ 3 green: 1 yellow
○ 4 green
○ 4 gg

Explanation:

Step1: Identify parent genotypes

Homozygous green: $GG$; yellow: $gg$

Step2: Determine gametes each parent produces

$GG$ produces only $G$ gametes; $gg$ produces only $g$ gametes

Step3: Predict offspring genotypes

All offspring inherit $G$ from green parent and $g$ from yellow parent, so all are $Gg$

Answer:

4 Gg
