In peas, high growth and yellow color dominate over short growth and green color of seeds, identify genoids and phenotypes F1 and F2 if homozygous tall peas with yellow seed color and undersized peas with green seeds are crossed.

Let’s designate the gene that determines the tallness of peas as B, then the gene for short stature will be b. Let’s designate the gene responsible for the development of yellow pea beans as C, then the gene for the green color of the beans will be c.

Homozygous tall peas with yellow beans, according to the introduced designations, are BBCC. Such peas will produce BC gametes.

Low-growing peas with green seeds will be vvss, since such traits can be realized in the plant phenotype only if they are due to the homozygosity of the plant genotype for these traits. Gametes produced by such peas are bc.

In the first generation, all pea plants will be tall, with yellow seeds – BbCc. Such hybrids are capable of producing germ cells: BC, bc, bC, and Bc.

The offspring of the second generation of peas will look like this:

high peas with yellow beans (BBCC, 4 BbCC, 2 BbCC, 2 BBC);

dwarf peas with green beans (bbcc);

dwarf pea plants with yellow beans (2 bbСс, bbСС);

tall plants with green beans (2 Bbcc, Bbcc).
