Question

In plants tall T is dominant to short t .perform the following cross Tt x Tt what is the probability of producing a short plant

Answer 1

25% or 1/4 chance

Step-by-step explanation:

When crossing these two heterozygous parents, you will get the phenotype 3:1. This means...

75% chance of plant being tall

25% chance of plant being short

Since T is dominant and we are using simple Mendelian inheritance, the heterozygous offspring (Tt) will be tall as well.

This means there is a 25% or 1/4 chance of the plant being short.
