Question

In the cattle allele for cloven hooves (H) is dominant over the allele for mule foot hooves (h). The phenotype for each trait is shown in the picture below. What is the probability of cloven hooves in the offspring of parents that are heterozygous for the trait

Answer 1

25%

Step-by-step explanation:

Answer 2

75 %

Step-by-step explanation:

If we take the genotype of both parents who are both heterozygous, the resulting cross would be:

Hh x Hh

Punnett square:

H h

H HH Hh

h Hh hh

As you can see thre are 3 possible genotypes and 2 phentypes:

HH 1 Cloven hooves

Hh 2 Cloven hooves

hh 1 Mule hooves

Because cloven hooves is dominant, it will be expressed even with the presence of the recessive allele.

So the probability is 3 out 4 or 75%
