- If a person is heterozygous in a certain gene, what is the chance that they will pass on their recessive gene to their offspring?
- Your father is not a carrier for an autosomal recessive trait, but your mother is. What is the likelihood that you will display the trait?
- One gene controls for having a widow's peak or not having one, and another gene controls for having straight or curly hair. Having a widow's peak is a dominant trait, and having…
