Abotanist is studying pea plants. one of the pea plants that she is studying is tall and has yellow flowers.

if the tall allele is represented by the letter t and the yellow allele is represented by the letter y, which of the following could be the genotype of the plant that she is studying?

a.) short and green
b.) tall and yellow
c.) ttyy
d.) ttyy

The correct answer is-

C.) TTYY

Genotype corresponds to the genetic makeup of an organism ( presented by gene variants, which are called alleles) that depicts particular morphological characteristic in the organism.

As per the information given in this question, one of the pea plants studied by the botanist is tall ( depicted by T allele ) and has yellow flowers ( depicted by Y allele).

Thus, the genotype of the plant that she is studying would be TTYY.

Therefore, option C) is the right answer.
