What are the odds that two carriers for cystic

Question

fibrosis, an autosomal recessive disorder, would have an offspring with the cystic fibrosis disorder?

Answer 1

The odds of two carriers for cystic fibrosis having an offspring with the disorder would be 25%. This is because when two carriers (each with one recessive allele and one normal allele) have a child, there is a 25% chance that the child will inherit two copies of the recessive allele and therefore have cystic fibrosis.
