Two pea plant with yellow peas are crossed most of their offspring have yellow peas but about 25% of the offspring have green peas for pee color yellow is the dominant trait in green is the recessive trait what does this tell you about the two parent plants

Both parents have the genes for yellow peas and green peas

Explanation:

If a plant has inherited one yellow peas gene and one green peas gene, the plant will produce yellow peas because (as you mentioned) yellow peas are dominant. that means the parents are heterozygous (Cc). If both parents have the gene versions Cc, then there is a 25% chance the offspring would get the gene version cc, coding for green peas.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
