Textbook Question
Chapter 7, Problem 5GP
Pfeiffer syndrome is a dominant genetic disease that occurs when certain bones in the skull fuse too early in the development of a child, leading to distorted head and face shape. If a man heterozygous for the allele that causes Pfeiffer syndrome marries a woman who is homozygous for the nonmutant allele, what is the chance that their first child will have this syndrome?

Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia.
They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square.

For a recessive condition, two normal heterozygous individuals have children.
What is the likelihood of their children being affected by this condition?
What is the likelihood of their children being carriers without the condition?
What is the likelihood of their asymptomatic children being carriers?
Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?
