Question

The Punnett square shows the possible genotype combinations of two parents who are heterozygous for a particular trait.

What is the probability of the parents having a child who is homozygous dominant for this trait?

0%
25%
50%
75%

Answer 1

Homozygous is when the two letters are the same and dominance is represented by capital letters. There is one square that has two capital letter so 1/4 is equal to 25%. Hope this helps

Step-by-step explanation:

B:)

Answer 2

25%

Step-by-step explanation:

The child only comes out as homozygous dominant (YY) for the trait in 1/4 boxes in the Punnett Square. This translates to the child having a 25% chance of being homozygous dominant for the trait.
