What offspring can be expected when crossing pea plants with yellow smooth seeds that are heterozygous for both traits?

Heterozygous plants show dominant traits in the phenotype. Let’s designate the gene that causes the yellow color of pea seeds as K. The gene for smooth seeds of this plant will be designated as L.

As a rule, the green coloration of the pea beans and the wrinkled shape of their surface are indicated as recessive traits. Let us designate these recessive features as k and l, respectively.

Heterozygous peas with yellow smooth seeds will be written as KkLl. Such plants are capable of producing four types of germ cells – KL, kl, Kl, kL.

Possible offspring from crossing such plants with each other will include the following options:

pea plants with smooth yellow colored beans (4 KkLl, KKLL, 2KkLL, 2KKLl) – 56.25%;

pea plants with wrinkled beans colored yellow (2Kkll, KKll) – 18.75%;

pea plants with wrinkled beans colored green (kkll) – 6.25%;

pea plants with smooth beans colored green (kkLL, 2kkLl) – 18.75%.
