Textbook Question
Chapter 12, Problem 15TYK
A mix-up in a hospital ward caused a mother with O and MN blood types to think that a baby given to her really belonged to someone else. Tests in the hospital showed that the doubting mother was able to taste PTC (see problem 9). The baby given to her had O and MN blood types and had no reaction when the bitter PTC chemical was placed on its tongue. The mother had four other children with the following blood types and tasting abilities for PTC:
1. type A and MN blood, taster
2. type B and N blood, nontaster
3. type A and M blood, taster
4. type A and N blood, taster
Without knowing the father’s blood types and tasting ability, can you determine whether the child is really hers? (Assume that all her children have the same father.)

Students have asked these similar questions
Two normal visioned parents have a color-blind son. Give the genotype of both parents and the son.
A male with B blood and a female with O blood are expecting a child together. Determine all possible blood types for their offspring. Drawing Punnett squares (2 X 2) as you do this will help. (Remember that blood types A and B can have 2 different genotypes and you need to take this into account in setting up your Punnett squares.)
Possible ABO blood types:______________________
If both of these individuals have Rh+ blood, is there any way they could produce a child with Rh- blood? (Be sure to consider the genotypes for Rh + individuals.) Explain your answer.
Mrs. Smith and Mrs. Jones had baby girls the same day in the same hospital. Mrs. Smith named her baby Selena and Mrs. Jones named her baby Jessica. Mrs. Jones began to suspect however that the babies had been switched. (This was in the day before DNA tests were possible.) Blood tests were done with the following results:
Mr. Smith type A
Mr. Jones type A
Mrs. Smith type B
Mrs. Jones type A
Selena type O
Jessica type B
Had a mix-up occurred? How do you know?

- Hemophilia is an X-linked disease associated with the inability to produce specific proteins in the blood-clotting pathway. Shown above is a family pedigree tree in which family members afflicted with the disease are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passing on the disease to their future children (represented by the ? symbol above) because the hemophilia runs in the woman’s family 4.Assuming that the woman in the couple is a carrier, what is the probability that the couple’s first son will have hemophilia?arrow_forwardWhat would the offspring's blood type be if the mother is type O+ (she is homozygous for Rh factor) and the father is A- (he is homozygous for type A)?
