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
A polydactylous, normal-visioned, brown-eyed man with wavy hair has a nonpolydactylous, blue-eyed mother. He proposed marriage to a nonpolydactylous, astigmatic, blue-eyed, and curly-haired lady whose mother has normal vision. However, the lady is worried about the proposal since sickle-cell anemia has been known to run in both their families.
If it turned out that the lady is a carrier and the man has normal RBC, what would be their COMPLETE genotypes?
Based on their genotypes, what is the probability that they would have:
1. nonpolydactylous child with normal vision?
2. polydactylous, astigmatic child and sickle-trait carrier?
3. a boy with his father’s genotype?
4. a girl with her mother’s genotype?
Jane (mother): Tt XcXc IBi -Taster, Color-blind female, Blood type B
John (father): tt XcY IAIB- Non-taster, Color-blind male, Blood type AB
Explain whether or not these two parents could possibly produce a normal visioned child who has blood type O?
Explain whether or not these two parents could possibly produce a color blind child, who could not taste PTC paper, and has blood type A?
What blood types could the children of this couple possibly have?
How many phenotypically different "kinds" of children could this couple produce? List a maximum of eight phenotypes.

Mrs. Kaur and Mrs. Sharma had babies on the same day at the same hospital. Mrs.
Kaur took home a girl (Harleen) and Mrs. Sharma received a boy (Baldeep). However,
Mrs. Sharma was sure she had given birth to a girl and brought a suit against the
hospital. Blood tests showed that Mr. Sharma was type O. Mrs. Sharma was type AB
and Mr. & Mrs. Kaur were both type B. Harleen was type O and Baldeep was type A.
Had a mistake occurred? Did the parents bring home the incorrect babies?
a. What is Mr.sharma genotype
b. What is Mrs.sharma genotype
c. What is Mrs. Kaur genotype
Has a switch occurred? Why or why not?

- 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?

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_forwardFamilial hypercholesterolemia (FH) is an inherited disorder in humans that is incompletely dominant.

- What 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)? Hint: You have to do two Punnett squares.
