Cystic fibrosis and Huntington’s are genetic conditions. Cystic fibrosis is a recessive condition and Huntington’s is a dominant condition. Draw the genetic diagrams to show the possible children for each of the couples below if... • Both parents are carriers of cystic fibrosis (Ff). • What is the chance of their child having cystic fibrosis? • What is the chance the child will only have one faulty gene? (carrier Ff) • One parent has cystic fibrosis the other parent hasn’t and isn’t a carrier. • One parent has Huntington’s (heterozygous Hh) the other parent is healthy (hh). • What is the chance that their child will have Huntington’s? • Can you be a carrier of Huntington’s? Explain your answer.
Draw the genetic diagrams to show the possible children for each of the couples below if... 1. 2. 25% 3. 50% 4. 5. 6. 50% 7. No because Huntington’s is a dominant condition. If you have the faulty allele you will have the condition. • Both parents are carriers of cystic fibrosis (Ff). • What is the chance of their child having cystic fibrosis? • What is the chance the child will only have one faulty gene? (carrier Ff) • One parent has cystic fibrosis the other parent hasn’t and isn’t a carrier. • One parent has Huntington’s (heterozygous Hh) the other parent is healthy (hh). • What is the chance that their child will have Huntington’s? • Can you be a carrier of Huntington’s? Explain your answer.
