Genes are segments of dna that determine the phenotype of an individual. pea colors can be yellow or green. when two plants that produce yellow peas were crossed, the offspring produced green peas. this is because the parents were for pea color. because there are only two options for pea color, the plants’ pea color is a case of

The correct answers would be:

Yellow pea plants cross to produce offspring with green pea. It is possible only when both the parents were heterozygous. Then only they would be able to produce offspring with yellow and green peas in the ration 3:1.

It is an example of simple Mendelian genetics or simple monohybrid cross as only two alleles (yellow and green) are involved in the production of phenotype (seed color).

The same is explained in the cross below.
