Answer:
Yes
Explanation:
Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.
Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.
The recessive trait only shows if a person has two recessive alleles.
Brown eyes is a dominant trait, and blue eyes is a recessive trait.
B = dominant brown eyes
b = recessive blue eyes
If someone has <u>brown</u> eyes, their genotype can be:
BB
Bb
If someone has blue eyes, their genotype is:
bb
The baby's genotype must be bb because it has blue eyes. <u>The baby gets one allele from each parent</u>.
See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.
