  1. During complete dominance, no matter what the trait is, when one crosses a homozygous dominant individual with a homozygoous recessive individual, the genotypic ratio will always be:

  2. 100% Heterozygous individuals

    50% homozygous dominant and 50% heterozygous

    25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive

    50% heterozygous and 50% homozygous recessive

Answer #1

Lets do this with the help of an example-

TT X tt

T T
t Tt Tt
t Tt Tt

As we can see that all are heterozygous. So, the correct answer is A.

100% are heterozygous.
