In a particular plant, two genes control height and flower color. Tall height (T) is dominant to short height (t). Yellow flowers (Y) are dominant to white flowers (y). A tall, yellow-flowered plant is mated with a short, white-flowered plant. What are the genotypes of the plants involved in this cross?

T_Y_ * ttyyTall Yellow plant, It may be = TTYY (homozygous dominant), or TtYy (heterozygous dominant). Short, white plant is = ttyy (homozygous recessive).

Explanation:

Given:

Tall = T,

short = t

T is dominant on t,

yellow = Y

white = y,

Y is dominant on y.

Cross between Tall Yellow plant, It may be = TTYY (homozygous dominant), or TtYy (heterozygous dominant).

Short, white plant is = ttyy (homozygous recessive).
