Question

Mr. and Mrs. Jones just had a baby. Mr. and Mrs. Jones both have brown eyes, but their new bundle of joy has blue eyes. Develop a model to show how this phenomenon is possible. If Mr. and Mrs. Jones had another baby, determine the probability that THAT baby would have blue eyes. What about brown eyes? Explain in detail.

Also, what are the phenotypes of the mom and dad?

Answer 1

Eye color in humans is determined by multiple genes. It is possible for parents with brown eyes to have a baby with blue eyes due to the complex inheritance patterns. The probability of the next baby having blue eyes depends on the genotypes of the parents.

Step-by-step explanation:

The eye color of an individual is determined by multiple genes. It is possible for Mr. and Mrs. Jones, who both have brown eyes, to have a baby with blue eyes due to the complex inheritance patterns of eye color. The blue eye color is a recessive trait, and both parents must carry the recessive allele for the baby to have blue eyes.

If Mr. and Mrs. Jones have another baby, the probability of that baby having blue eyes would depend on the genotypes of the parents. If both parents are heterozygous carriers of the blue eye allele, there is a 25% chance that the baby would have blue eyes. If both parents are homozygous for the brown eye allele, there is no chance of the baby having blue eyes.

The phenotypes of Mr. and Mrs. Jones are brown eyes, as they both have brown irises.
