A woman with blood type O has a child with blood type B. She accuses a man with blood type A of being the father of her child. What is the woman’s (mother’s) blood genotype? What is her child’s blood genotype? What is the chance that this man is the father of her child? (Show in the following punnett square) What must the man’s blood genotype be if he is the father?

6) Mike has type B blood and his wife lynn has type O blood. They are very shocked to hear that their baby has type A blood, and think that a switch might have been made at the hospital. a. What is the genotype of the baby? b. What are the possible genotypes for Mike? c. What are the possible genotypes for lynn? d. Can this baby be theirs? Why or why not? 1) A dad is type A homozygous,...

A type A woman is the daughter of a type O father and type A mother. If she has children with a type AB man, what is the probability that they have an “A” blood type first child but a “B” blood type second child, and a “AB” blood type third child?

A woman has type A blood that is Rh-negative. Her father, however, had type B blood that was Rh-positive. She marries a man who is AB positive, but his mother was Rh-negative. I know that the allele for Rh positive blood is dominant (R) over the allele for Rh-negative blood (r). But I am having trouble with a 4x4 Punnett square which I am sure would be essential to solving this! I appreciate any help you could give! 1. What...

Sex Linked Traits 4. Assume you are a genetic counselor and a couple comes to you for counseling They want to know if there is any chance that their first baby might have muscular dystrophy. M.D. is a sex linked recessive trait. Neither of the parents has M.D. but the wife's father has M.D. Prove your answer by showing the genotypes and phenotypes of the parents, grandparents and possible offspring.

8 A case of disputed paternity involves a woman, her children (1, 2 and 3), and two men Y and Z). The analysis is limited to the ABO and Rh blood group systems. Using the space below, and assuming that only YorZ could be the biological father, assign each child to his/her possible father. You can use either Punnett squares for each trait, or the process of Mother Possible Fathers Children Possible father for each child elimination. There may be...

What is ken’s genotype? c. What is the only possible genotype for Atia? d. What is the only possible genotype for Min? 5) jane has type AB blood. Her husband Pat has type AB blood.

6. If you cross a woman with type A blood and a man with type B and both ha dominant and one recessive allele for blood type what are the possible genotypes of their offspring? Use the Punnett square below to help you determin etermine this. 7. Choroideremia is a disease that causes degeneration of the retina of the eye. The recessive allele that causes this condition is found on the X chromosome. Using the square below, cross a woman...

the two cream colored guinea pigs produced, in one case, 22 yellow. 47cream, and 19 white. What type of inheritance is this? II. Sex-linked Characteristics 12. In man, colorblindness, an inability to distinguish between red and green, is inherited as a sex-linked character on the X chromosome. It is recessive. If a colorblind man marries a homozygous normal woman what chance is there for the children of being colorblind? If a normal man marries a colorblind woman. where will colorblindness...
For these questions, you are using the A, B, and O to represent the alleles in...
For these questions, you are using the A, B, and O to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood...
