Explain the ABO blood system as an example of multiple alleles and codominance; be sure to discuss blood
Step by step
Solved in 2 steps
- Describe how the Bombay phenotype is epistatic to the ABO blood phenotype in humans, and discuss some implications of this phenotype in blood typing and blood donation.Hemophilia is inherited as a sex-linked recessive trait. A non-hemophilic man marries a non-hemophilic woman whose father had hemophilia. With respect to this information, indicate all possible genotypes their children could possibly have. Show ALL work using punnett squares.A normal woman, whose father was a hemophiliac, marries a normal man. Determine the genotype of the woman and the man. Determine the possible genotypes of their children. What percent of male and female children would be hemophiliacs? What percent normal? Would any be carriers?
- Mrs. Reyes is a. carrier of the sex-linked hemophilia allele (XAXa) and Mr. Reyes is normal (XAY) What are the theoretical genotypes and phenotypes among their children? If the have 4 male and 4 female children; how many of each sex would be expected to be hemophiliacs, carriers and normal?Define the allele associated with this form of anemia, and define the NORMAL allele of this same gene. Be sure to indicate which is which.If an AB negative (blood type) female mates with an O positive male (blood type). What are the potential offsprings? Preferably shown through a punnet grid, other means of representation are also accepted if percentages are accurate.
- Draw a punnet squareshowing the cross of the following scenario and the possible percentages of each blood type: A person with type B blood (genotype BO) has children with a type AB person. What blood types are possible among their children?A 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).With regard to the ABO blood types in humans, determine the genotype of the male parent and female parent shown here: Male parent: Blood type B; mother type O Female parent: Blood type A; father type B Predict the blood types of the offspring that this couple may have and the expected proportion of each.
- In a maternity ward, four babies become accidentally mixed up. The ABO blood type of the four babies are known to be O, A, B and AB. The ABO types of the four sets of parents are determined. Indicate which baby belongs to each set of parents below: a) AB X O b) A X O c) A X AB d) O X OA man who has B blood type is having a child with a woman who has A blood type. Predictthe possible blood type for their child.A survey was taken to determine the blood types of children from marriages in which the wife had the blood group AB and the husband had blood type A but one of his parents is type O. The survey resulted in 250 type A, 90 type B, and 110 type AB children. Is the deviation from the expected significant?
