Answer: Based on the information provided, the pea color in this case is a dominant-recessive inheritance pattern.
Explanation: We know pea color can be yellow or green.
Crossing two yellow pea plants produced green offspring.
This suggests yellow is dominant (expressed even if paired with a recessive gene) and green is recessive (only expressed when paired with another recessive gene).
Therefore, the parents must have carried both dominant and recessive alleles for pea color, even though they produced yellow peas themselves.
