Tay Sachs disease is an autosomal recessive trait. A young couple had their first

child affected with Tay Sachs. What is the risk that their future children will be

similarly affected?

What does it mean when a trait is

autosomal dominant?

If you cross a heterozygous parent with a homozygous recessive parent, what is

percentage of offspring that will show the dominant

trait?

If you cross a homozygous dominant parent with a homozygous recessive

parent, what percentage of their offspring will be

heterozygous?
