Earl has normal color vision, while his wife Erma is colorblind. Determine the probability of their children being – Females who are red-green colorblind? Females who are carriers of red-green color­blind? Females who are NOT carriers of red-green colorblind? Males who are red-green colorblind? Males who are NOT red-green colorblind? b. Mary’s father is red-green colorblind, as is her maternal grandfather (her mother’s father). Mary herself has normal color vision. Mary and her husband, Steve, who is also colorblind, have just had their first child, a son they have named Bill. What is the probability that Bill will be colorblind? Explain your answer. c. In b above, three sources of the colorblindness allele are mentioned in this family. If Bill is color­blind, from which of these three men (Mary’s grandfather, Mary’s father, or Steve) did he inherit the allele? Explain your answer. d. In b, above, if Steve were not colorblind, how would this affect the prediction about Bill? Explain your answer. Does the fact that Steve is or is not colorblind, change the chances of their next child, Susan being colorblind? • Show less60
