Genotype of Parents:
- The man has blue eyes and red hair, which means he must have the genotype bbrr.
- The woman has blue eyes and dark hair, which means she could have the genotype BBDD or BbDD.
Genotype of the First Child:
- The first child has brown eyes and red hair, which means they must have received one dominant B allele for eye color from the mother and one recessive rr allele for hair color from the father.
- Therefore, the genotype of the first child is Bbrr.
Genotype of the Second Child:
- The second child has blue eyes and dark hair, which means they must have received the recessive bb allele for eye color from both parents and one dominant D allele for hair color from the mother.
- Therefore, the genotype of the second child is bbDD.
Explanation:
- Eye color and hair color are controlled by different genes, so they do not necessarily follow the same inheritance pattern.
- In this case, brown eyes are dominant to blue eyes, and dark hair is dominant to red hair.
- The man has blue eyes and red hair, which means he must have received a recessive b allele for eye color and a recessive r allele for hair color from both parents.
- The woman has blue eyes and dark hair, which means she has at least one dominant B allele for eye color and at least one dominant D allele for hair color.
- The first child received a dominant B allele from the mother and a recessive r allele from the father, resulting in brown eyes and red hair.
- The second child received recessive b alleles from both parents for eye color and a dominant D allele from the mother for hair color, resulting in blue eyes and dark hair.
