4. because men have only one X chromosome
5. Males transmit their Y chromosome to their sons. This means that sons will not inherit an X-linked recessive condition from their father.
6. Because O is recessive and A and B are dominant, both parents could be carrying an O form of the gene without it being apparent (AO mother and BO father, for example). If their baby inherited the O from each of them, the baby would have an O blood type.
a. b.
8. Because Huntington's usually doesn't affect the victim until about the age of 40, they have time to have children and pass the on the gene
9. No, because each child's 2 sets of chromosomes are rearranged independently, so that there is an equal probability of all of them having the same genotype (1/2^4, or 1/16) as there is of them having all different ones
10. Type A: The genotype is either AA or AO. The antigens on the blood cell are A and the antibodies in the blood plasma are B.
Type B: The genotype is either BB or BO. The antigens on the blood cell are B and the antibodies in the blood plasma are A.
Type AB: The genotype is AB. The antigens on the blood cell are A and B. There are no A or B antibodies in the blood plasma.
Type O: The genotype is OO. There are no A or B antigens on the blood cell. The antibodies in the blood plasma are A and
