in pea plants, tallness (t) is dominant to shortness (t). what are the predicted percentages of the genotypes 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). what are the predicted percentages of the genotypes 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

Answer

Explanation:

Step1: Determine parental genotypes

The homozygous short - plant has genotype tt, and the heterozygous tall plant has genotype Tt.

Step2: Set up Punnett - square

The possible gametes from the tt plant are all t. The possible gametes from the Tt plant are T and t.

t
T Tt
t tt

Step3: Analyze genotypes of offspring

From the Punnett - square, we can see that the genotypes of the offspring are Tt and tt. There are 2 Tt and 2 tt out of 4 possible genotypes. So the percentage of Tt is $\frac{2}{4}\times100% = 50%$ and the percentage of tt is $\frac{2}{4}\times100% = 50%$.

Answer:

50 percent Tt, 50 percent tt
