In pea plants, tallness (t) is dominant to shortness (t). what is the predicted genotypic ratio of the offspring if a homozygous short plant is crossed with a heterozygous tall plant? 25 percent tt, 75 percent tt 25 percent tall, 75 percent short 50 percent tt, 50 percent tt 50 percent tall, 50 percent short

It doesnt matter if it´s a,b,c or d as long as one of those choices has 25 percent Tt, 75 percent tt in it...

The right answer is 50 percent Tt, 50 percent tt

The analysis and statistical interpretation of gene distribution in such crosses is the foundation of classical genetics.

Genetic crossbreeding is a process of crossing species to obtain (new generation) hybrids.

Let's do the cross.

Tt x tt

Tt, Tt, tt, tt.

So we conclude that it gives us 50% of heterozygotes (Tt) and 50% of homozygotes of small size (tt).
