Textbook Question
Chapter 16, Problem 15QP
A couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the woman’s family but not in the man’s family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?

Imagine you are a genetic counselor and a couple has come to you to learn more about their genetics and the effects genetic inheritance will have on their baby. Describe which traits are inherited from parents and an explanation of how they are received from genes. What are common dominant traits in a family?
Create a hypothetical person and situation as a real life example to illustrate your position. Who is this person? How old is this person? What chromosomal abnormalities does this person have? How does genetic testing and counseling make this person’s life better or worse? Ultimately, should your hypothetical person seek genetic counseling?
Please explain why sex linked recessive traits are inherited by the son from his mother. If a mother is a carrier, what percentage of her sons will have the trait? Please give me example of sex linked recessive trait.
