1. A woman with type B blood gives birth to a girl who is type O. Which of the following men could of been the father (a) Joe- Type O (b) Frank -Type B (c) Steve- Type AB (d) both Joe and Frank (e) Joe, Frank or Steve In mice, coat color is due to the inheritance of three genes located on three different chromosomes. The A gene which determine if a yellow band is present on the hair (A= yellow band, aa=no yellow band ) and the B gene which determines if the hair is brown (bb ) or Black (B). The A and B genes interact to produce the following coat colors: Agouti: AB Cinnamon: A bk black: brewn aabb The third gene is the C gene, which determines if the mice has any hair pigment at all. If the mouse has at least one C allele then the coat color will be determined by the A and B genes as described above. However, if the mouse is cc in genotype it will be albino, regardless of the mouse's A and B genotype. aaB 2. In mice coat color (a) the C gene is dominant to the A and B genes (b) the cc genotype is epistatic to the A and B genes (e) the C gene is codominant to the A and B genes (d) The A gene is X-linked (e) none of the above 3 If a AabbCe mouse mates with a aaBbcc mouse, what is the probability that a mouse will be born an albino? (a) % (b) % (c) 1/16 (d) 3/16 (e) none of the above 4. If a AabbCc mouse mates with a aaBbcc mouse, what is the probability that the mouse will be born brown? (a) % (b) %c) 1/8 (d) 1/16 (e) none of the above 5. A couple have a boy who is bom with color blindness (a sex linked recessive disorder). If both parents have normal color vision what are the chances that their second child (a new bom girl) will also be color blind (a) 0% (b) 25% (c) 50% (d) 100% (e) because the couple has already had one boy with colorblindness it is very unlikely that their second child will also be color blind 6. CGH a sex-linked dominant that causes individuals to be covered with hair. If a nomal man marries a girl with CGH (her father was also CGH but her mother was normal) what are the chances that her first bom will also have CGH? (a) 0% (b) 25% (c) 50% (d) 75% (e) 100%
