a. 3
b. 4
c. 5
d. 6
e. 2

Answer 1

Option A, 3

Step-by-step explanation:

Primarily all pea seeds have two colors one is yellow and other is green.

Let green color allele be represented by "G" and yellow color allele be represented by "g".

When we start working on pea seed color problem, there can be following possible genotypes -
