Answer:

b. 50% chance of yellow skin

Step-by-step explanation:

The likelihood that their kid will have yellow skin depends on the genetic makeup of both Patterson and Petunia. Patterson has the genotype Pp, which means he has one dominant allele for pink body color and one recessive allele for yellow body color. Petunia, on the other hand, has the genotype pp, which means she is homozygous recessive for yellow body color.

When they have children, each parent will contribute one of their alleles to their offspring. The offspring will have a 50% chance of inheriting the recessive allele for yellow body color from Patterson and a 50% chance of inheriting the recessive allele for yellow body color from Petunia. Therefore, the likelihood that their kid will have yellow skin is 50%.
