Question

In pea plants, the allele for tall plants is dominant to the allele for short plants. If a homozygous tall plant is crossed with a homozygous short plant, what percent of offspring would you expect to be short?
0 percent
25 percent<--- my answer
50 percent
100 percent

Answer 1

The percentage would be 50

Answer 2

Answer:

0%

Explanation:

So a homozygous dominant tall plant would be TT, and a homozygous recessive short plant would be tt. If you put these into a punnett square, you would get 4 Tt's since each offspring gets one allele from each parent and being tall is dominant. The phenotype of Tt (what it looks like) is tall which means they are all tall and none are short.
