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.a. genotype; Bb
b. genotype; bb
c. phenotype; Bb
d. phenotype; bb

As wendy's mother has blue eyes and blue eyes is controlled by recessive allele therefore she must have genotype bb. As wendy father is having brown eyes then he can have genotype BB or Bb.

Therefore as a mother is homozygous recessive so one recessive allele will come from father and for brown eyes phenotype dominant allele is important. So wendy must have genotype Bb.

B b B B

b Bb bb b Bb Bb

Therefore for having brown eyes, Bb genotype is the only genotype that wendy can posses.

Wendy’s genotype must be bb if she has blue eyes.

The unit of inheritance is the gene. The gene is a molecule that contains information about the cells in the form of codons.

Genes often occur in pairs called alleles. In each pair of allele, one gene is dominant (expressed) while the other is recessive(not expressed).

The sum total of genes that an organism receives from its parents is called the organism's genotype.

If Wendy has blue eyes then she received the two recessive genes bb.
