Problem 68. If 2 spot (S) is dominant to 4 spot (s), give the genotypes for the parents in the following crosses: (a) 2 spot 2 spot yields 2 spot and 4 spot  (b) 2 spot 4 spot yields only 2 spot  (c) 2 spot 4 spot yields 2 spot and 4 spot  (d) 2 spot 2 spot yields only 2 spot  (e) 4 spot 4 spot yields only 4 spot  69. The allele for albinism (c) is recessive to the allele for normal pigmentation (C). A normally pigmented woman whose father is an albino marries an albino man whose parents are normal. They have three children, two normal and one albino. Give the genotypes for each person listed. 70. Crosses between a yellow rat with a yellow rat always produce yellow. Crosses between a white rat with a white rat always produce white. The alleles affect the same aspect of coat color. The crosses of a white with a yellow produce a cream. What happens if you cross two creams? 71. are three alleles controlling the ABO blood types. and are codominant genes so that the IA IB combination produces the AB blood type. The third allele, is recessive to the other two alleles. IAIB IO, Indicate which of these parents could produce the given child: Parents Child Yes or No (a) B A  AB (b) A A  O (c) O A B  (d) O A AB  (e) B A AB  (f) O B B  (g) A AB AB  72. If a father and a son are both color blind and the mother is normal, is it likely that the son inherited color blindness from his father? 73. Hemophilia is caused by an X-linked recessive gene. A normal woman whose father had hemophilia marries a normal man. What are the chances of hemophilia in their children.
