Start with the P generation with the following genotypes (AA x aa). Based on classical Mendelian inheritance, how will a cross between two homozygous parents, one dominant, one recessive, influence future generations?

Back

Although the F1 generation will all show the dominant trait, the offspring will all be heterozygous and increase the chances of future variation.

A couple has three brown-eyed children. The parents are brown-eyed (Bb). The allele for brown eyes is dominant over the allele for blue eyes. What is the chance their fourth child will be blue-eyed?

Back

They have a 25% chance of having a blue-eyed child.
