Fatty acid metabolism disorder is an autosomal recessive disorder. Two unaffected parents have 6 children – 3 of whom are affected, and 3 of whom are unaffected. 

5) What are the chances that this couple will have an unaffected child?
6) What are the chances that this couple will have an affected child?

Hemophilia is a sex-linked recessive disorder.

If an unaffected woman mates with an unaffected man, and they have 3 children with hemophilia, and one child who is unaffected,

9) What are the chances that the couple will have a child with hemophilia?
10) What are the chances that the couple will have a boy who has hemophilia?
11) What are the chances that the couple will have a girl who does not have hemophilia?

12) What is the woman’s genotype?
13) What is the man’s phenotype?
14) What are the chances that this couple produces a child with long eyelashes?
15) What are the chances that this couple produces a child with dimples AND with long eyelashes?
