mother has A blood type has a child of B blood type. What are all the possible genotypes of the father

In a parental cross for an autosomal MOI, the ratio (Disease phenotype):(WT phenotype) differ for the scenarios: (i) the father is affected and mother is unaffected; and (ii) the mother is affected and the father is unaffected.  a) true  b) false

Billy and Shiva just had a baby girl and are worried that there may have been a mix up at the hospital. Billy has A type blood, and Billy's father has O-type blood. Shiva has B type blood, and Shiva's mother had O-type blood. Their baby has O-type blood. Which of the following is true? O There must have been a mix up, as Shiva and Billy could only have a child with A, B, or AB blood. The baby could be Shiva and Billy's, as they are both hybrid for blood type and could pass the recessive allele to their child. This baby could not be theirs, as O type blood is dominant, and either Shiva or Billy would need to have O-type blood to pass it to their child. None of the above are true. 82%4 A * .

ABO blood groups, an autosomal trait, in Humans are genetically determined. A woman with type O blood has a son with type O. What are the possible genotype(s) of the son, his mother and possible father?                 Mother:                Father:                 Son:

Hemophilia is an X-linked disorder that affects the body’s ability to create blood clots. The allele for normal blood clotting, XH, is dominant over the allele for hemophilia, Xh. An unaffected daughter from the above cross married a man who does not have hemophilia. Determine the probability of their offspring being A daughter with hemophilia A daughter without hemophilia A son with hemophilia A son without hemophilia Express your answer as a phenotypic ratio. Number: Answer Answer Answer Answer Phenotype: Affected female Unaffected female Affected male Unaffected male

A parent with Type A blood and a parent with Type O blood have a child. Which of the following is a possible genotype of their offspring?

Crossing over (that can be measured) occurs between:

A couple finds out that both the male and the female are heterozygotes (carriers) for Tay Sachs. Draw a punnet square for this couple. What is the likelihood that this couple will have an offspring with Tay Sachs?

A mother is heterozygous for the X-linked gene for colorblindness and also heterozygous for the autosomal inherited sickle cell anemia. She is married to a man who can see color normally and who is heterozygous for sickle cell trait. Using b (colorblind), B (normal color), S (normal hemoglobin), s (sickle cell), answer the following: a. What are the genotypes of the parents? b: What is the probability of having a child who is both color blind and has sickle cell anemia?
