Answer: There is 100% chance that the pea plant will have green pods.

Explanation

Yellow pod color is recessive trait and green pod color is dominant trait. Let the allele for the yellow pod color be 'Y' and for the green pod color be 'y'.

Genotypes of the parents according to the question are-

Yy (hetrozygous plant) and YY (homozygous dominant plant)

When these parents are crossed, there is a 100% chance that the pea plant will have green pods. This is because the dominant allele Y is present in all the offsprings. This gives them a green pod color.
