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

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

Answer: The correct answer is-  50 percent Tt, 50 percent tt.

In pea plants tallness ( depicted by T allele) is a dominant trait over shortness ( depicted by t allele), which is a recessive trait. The possible genotypes of tall are Tt and TT whereas for short plant is tt.

As per the question, genotype of parents is - tt ( homozygpus short) and Tt ( heterozygous tall).

The gametes produced by tt are 't' and 't' whereas by Tt are 'T' and 't'.

When these parents are crossed, they will produce 50 percent Tt, 50 percent tt offsprings.
