Question

question 1
how many genetically different gametes can a pea plant produce if it is heterozygous for stem length and homozygous for pod color (ttgg)?
1
2
4
3
8

Explanation:

Step1: Analyze the alleles for each trait

For stem length, the plant is heterozygous \(Tt\). For pod color, it is homozygous \(GG\).

Step2: Use the formula for number of gametes

The formula for the number of different gametes produced is \(2^n\), where \(n\) is the number of heterozygous gene pairs. Here, \(n = 1\) (only the \(Tt\) pair is heterozygous).
So, \(2^1=2\)
