Question

Wendy's mother has blue eyes and her father has brown eyes. The allele for brown eye color is dominant (B) to the allele for blue eye color (b), but Wendy has blue eyes. Therefore, Wendy's ________ must be ________ and her father's must be Bb.

genotype; Bb
genotype; bb
phenotype; Bb
phenotype; bb

Answer 1

Wendy's mother has blue eyes, which means her genotype must be **bb** (since blue is recessive). Wendy also has blue eyes, so her genotype must also be **bb**. Since her father has brown eyes, his genotype must be **Bb** (heterozygous, carrying one allele for brown eyes and one for blue).

Therefore, the correct completion of the sentence is:

Wendy's **genotype** must be **bb** and her father's must be Bb.

The answer is: **genotype; bb**.
