A person who inherits only one copy of allele will be unaffected, however if two such people have a child the child could inherit two copies of allele.....

Key: C normal allele/c disease allele
1. A healthy man and a healthy woman have a child who has cystic fibrosis. Identify the genotypes for this trait for both parents and for their child.
2. This man and woman want another child. Calculate the probability that the second child would have cystic fibrosis.
3. Calculate the probability that a third child would have cystic fibrosis.
4. More serious genetic diseases are caused by recessive alleles then by dominant alleles. Explain why this is the case.
I know how to make a punnett square, i just don't know how to calculate the probabilities, im not sure what a genotype is
