Question

Assume that tall is dominant to short. In a cross of heterozygous pea plants to pure-breeding short ones

Answer 1

When crossing a heterozygous tall pea plant with a pure-breeding short one, the genotypic ratio of the offspring is 1:1.

Step-by-step explanation:

In this cross between a heterozygous tall pea plant and a pure-breeding short pea plant, the genotype of the heterozygous tall plant would be Tt, while the genotype of the pure-breeding short plant would be tt. Using a Punnett square, we can predict the genotypes of the offspring. When we cross Tt with tt, the possible genotypes of the offspring are Tt and tt, with a genotypic ratio of 1:1.
