What is the probability that a child will be born with a recessive trait if both parents are heterozygous for the trait?

How many chromosomes are in a normal haploid human cell?

In dominant-recessive inheritance, if an individual is heterozygous, which phenotype will be expressed?

The form of inheritance in which the heterozygous state is expressed as an intermediate is __________.

A person who inherits the A and the O blood type alleles will possess which blood type?

In the human blood type AB, both alleles are expressed and are therefore __________.

If the allele for brown hair is represented by B, it means that __________.

Heterozygous parents who have had one child with a recessive disease have a __________% chance of having a second child born with the same recessive disease.

Use the following information to solve the problem using a Punnett square: Assume that the dominant B allele encodes brown eyes and the recessive b allele encodes blue eyes. An individual with the genotype bb has children with an individual of the genotype Bb. What is the percent chance that they would have children with blue eyes?
