The potential genotypes for newborns with brown eyes are BB and Bb, whereas the potential genotype for newborns with blue eyes is bb.

According to the information provided above, b = allele for blue eyes is recessive while B = allele for brown eyes is dominant.
A recessive allele is one that cannot express itself in the presence of a dominant allele, while a dominant allele conceals the effect of a recessive allele.
A dominant allele expresses itself in the presence of a recessive allele.
While a dominant allele can express itself in both a homozygous and heterozygous state, a recessive allele can only do so.
Therefore, newborns with brown eyes will have two genotype options: BB and Bb, whereas those with blue eyes will only have one.
