Question

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

What is the probability of the parents having a child that is heterozygous for this trait?



A.0%

B.25%

C.50%

D.100%

Answer 1

100 percent

Step-by-step explanation:

its isnt 25 percent

Answer 2

Heterozygous refers to a pair of alleles in which one is dominant and one is recessive. As you can see, all genotypes for possible offspring in the Punnett square are heterozygous. This means the probability of the parents having a child that is heterozygous is 100 percent likely.

Answer:
D. 100%
