Answer:
Green peas if it does not have a dominant allele for yellow peas.
Explanation:
In pea plants, yellow is the dominant allele color of peas and green is the recessive allele color of the pea. So the genotype that makes yellow color pea is YY or Yy and the genotype that is responsible for producing green color pea is only YY.
This shows that homozygous dominant or heterozygous dominant condition gives rise to yellow color pea and only homozygous recessive condition would give rise to green color pea plants.
Therefore if a pea plant has the recessive allele for green peas it will produce green peas if it does not have a dominant allele for yellow peas.
