A test was done to determine the biological father of a child. The child's blood Type is A and the mother's is AB. Man
#1 has a blood type of B, & man #2 has blood type O.
a.
Which man is the biological father?
b. Draw a Punnett square to show the cross between the father and mother that resulted in this child, noting
the genotypes of the mother, father, and the child.
Joe has classic hemophilia, an X-linked recessive disease. Could Joe
have inherited the gene for this disease from the following people?
Yes
No
a. His
mother's
mother
b. His
mother's
father
c. His
father's
mother
d. His
father's
father
The genetic disease hemophilia A is a sex-linked trait. Jane has an uncle on her father's side of the family who has hemophilia A, her father does not have hemophilia A. On Jane's mother's side of the family there has never been a case of hemophilia A. Should Jane be concerned about passing the gene for hemophilia A to her own children? Explain your answer.
