Chapter 19, Problem 6CT
The ABO blood system has been used to settle cases of disputed paternity. Suppose, as a geneticist, you must testify during a case in which the mother has type A blood, the child has type O blood, and the alleged father has type B blood. How would you respond to the following statements?
- a. Man’s attorney: “The mother has type A blood, so the child’s type O blood must have come from the father. Because my client has type B blood, he could not be the father.”
- b. Mother’s attorney: “Further tests prove this man is heterozygous, so he must be the father.”

- If a woman has blood type A and a man has blood type O, what are the possible blood types of their children? Hint: you will need to set up more than one Punnett square herearrow_forwardA mother wants to see her baby. But the three babies in the nursery lost their ID bracelets, using a blood test, the mother is homozygous type A and the father is type O. The babies have blood types AB, A, and O. Which is the baby of this couple? Explain your answer.arrow_forwardA woman with blood type B has a child with blood type O. Her husband, whose blood type is A is concerned that the child may not be his. Based on what you learned from the inheritance of the ABO blood group system, what conclusions would you make? (Assume that both parents and the child normally produce the H-substance). The husband should not be concerned because the A and B blood types from the parents cancel each other in the child to produce an O type. The husband is right to be concerned because neither of the parents have O type blood. The husband is right to be concerned because only the blood types A or B are possible in their child. The husband is right to be concerned because only the blood groups A, B, or AB should be possible in their offspring. The husband should not be concerned because he and his wife may each be carrying an O allele.arrow_forward
