Textbook Question
Chapter E, Problem 11P
In an inheritance case, a man has died leaving his estate to be divided equally between “his wife and his offspring.” His wife (M) has an adult daughter (D), and they argue that they should split the estate equally. As a young couple, however, the man and his wife had a son that they gave up for adoption. Two men have appeared, each claiming to be the son of the couple and therefore entitled to a one-third share of the estate. The accompanying illustration shows the results of DNA analysis for five genes for the mother (M), her daughter (D), and the two claimants (
a. How many nonmaternal DNA bands are shared by D and
b. Do the DNA results suggest that either man is likely to be the son of the man and his wife? Explain.

Two claimant fathers filed a case against a lady claiming to be the father of her only daughter. How could this case be settled identifying the real biological father?
Tom and Jane have four children: two girls, Jill and Janet, and two boys, Tim and Todd. Tim has a genetic disorder that gives him polka dotted finger nails, but Todd Jill and Janet do not. All four of the children get married (to people outside their family) and have children. Here are the results:
Jill’s ChildrenJack affected with polka dot finger nailsJacob NOT affected with polka dot finger nailsJohn affected with polka dot finger nails
Janet’s ChildrenJason NOT affected with polka dot finger nailsJustin affected with polka dot finger nailsJessica NOT affected with polka dot finger nails
Tim and Todd have NO children affect with polka dot finger nails
This genetic disorder is mostly likely:

Baby Samuel died at the age of nine days. When baby Matthew has trouble feeding, his parents take him in to the doctor. He is diagnosed with Maple Syrup Urine Disease (MSUD), a life- threatening condition in which the patient is not able to break down proteins from their food. As Matthew receives treatment, Jacob and Emma are referred to a genetic counselor. The genetic counselor collects information about their family. Neither of Jacob's parents were affected by MSUD. Jacob had one brother and three sisters. One of these sisters died shortly after birth. Similarly, neither of Emma's parents were affected by MSUD. Emma had four brothers, and two of these died shortly after birth. a. Given what you know about Jacob and Emma's family, construct a pedigree that includes all three generations. b. Based on the pedigree you constructed, is it likely that MSUD is caused by a dominant allele or recessive alleles? How can you…arrow_forward
