You are trying to find a blood donor to help treat some of your patients.
The C-yonce and Kay-Z have 3 children with blood types A , B, and O. The youngest with blood type O needs a transfusion and you're trying to figure out if either of the parents are a match so you test the parent genotypes.
Note: Alleles for each blood type are expressed as follows:
blood type A= I^A
blood type B= I^B
blood type O= i
Hint: Remember that 2 alleles contribute to a persons blood type. Pay attention to dominant and recessive relationships among the alleles.
1-C-yonce is type B. What must her genotype be?
2-What must Kay-Z’s genotype be?
3-Which parent can give blood to their child ?
4-After running lab tests, it was discovered that the children's blood types were reported incorrectly.(This does not affect the genotypes entered for C-yonce and Kay-Z in the previous questions.) Their youngest actually has blood type AB, and still needs a blood transfusion. Which parent can donate blood to the child…

Which of the following statements regarding Mendel's observations and Laws are
still true and part of our knowledge of genetics today? (Check all that true.)
M Two alleles segregate during meiosis, ending up in different gametes.
Each pea plant has 2 alleles for every gene, but only contributes one in each gamete.
The recombination of alleles in a zygote is completely random.
The Law of Independeht Assortment was determined by following three traits in pea
plants,
TMendle was able to determine his Law of Segregation by following ane trait in pea
plants.
Every offspring inherits only 1 allele from each parent.
In a paternity suit, a woman with type O blood claims that a man with type AB blood is the father of her type O baby. List the genetypes of the mom, man, and baby. Can the woman prove he is the father or can he is not? Why or why not? If the accused man was type A insyead of type AB, what would be his possible genotypes? Could the woman prove he is the father? Can the man prove he is not the father? Why or why not?

- Use the image below to answer the following questions. Label the genotypes for ALL the family members in the pedigree above. Remember to use XX and XY when labeling. What does it mean to be a carrier? Why does Alexis have hemophilia? Is hemophilia a sex-linked disease? What does that mean and how does this pedigree show you this?arrow_forwardA couple consulted a genetic counselor and they found out the following: Basha: A blood type, blue eye color, normal skin condition, carrier of cystic fibrosis gene, and carrier of hemophilia gene Popoy: B blood type, has brown eye color, normal skin condition, carrier of cystic fibrosis gene and negative to hemophilia. Clues for the table: • Blood Type: The probability that they’ll have an offspring with blood type the same as Popoy is 25% only • Eye Color: The probability that they’ll have an offspring with brown eye color is 75%. • Skin condition: The probability that their offspring will be an albino is 25% What is the probability that the offspring will have/ be: A. a girl with all the same phenotype as her mother. B. 2 girls with neither the blood type of the parents. C. 2 boys with normal skin color and carrier of cystic fibrosis gene; 1 girl with normal skin color and negative to cystic fibrosis.

The trait is controlled by a recessive allele found on 4. the X chromosome. An affected son was born to a man and woman who were unaffected. The woman's mother was affected while the father was normal. a. Indicate the gene notation. b. Give the genotypes of the affected boy's parents.

- In the 1940’s, a young actress filed a case against a film director, Robin Williams, for parental support of her illegitimate child. Robin Williams’ blood type was already on record as type AB. The mother of the child had type A and her son had type O blood. A. Complete a Punnett square for all possible crosses of Robin and the mother.B. The judge ruled in favor of the mother and ordered Robin Williams to pay childsupport costs of the child. Was the judge correct in his decision based on blood typingevidence? Explain why or why not.arrow_forwardUse the following information to answer the next question. In humans, the allele for normal blood clotting, H, is dominant to the allele for hemophilia, h. The trait is X-linked. A woman who is not a hemophiliac has a father who is a hemophiliac. If this woman has a child with a man who is a hemophiliac, what is the probability of them having a hemophiliac son? (Record your answer as a frequency between 0 and 1 rounded to two decimal places. Include the decimal.) Answer: Answerarrow_forwardSituation: Guinevere decides to trace the inheritance of her blood type through her family, all the way back to her great-grandmother Natalia. Guinevere's great-grandmother Natalia, has type A blood. Natalia and her husband Claude have five children-three sons, Miguel (who has blood type A), Mark (who has blood type B) and David (who has type AB blood); a daughter (Jane) with type O blood and another daughter (Janella) with type A blood. Jane marries a man and they have two sons (Marco and Polo) who both are blood type A and a daughter (Mara) who has blood type B; Janella on the other hand marries a man and together have three sons (one with blood type A, one with AB, and one with O). Miguel marries a woman with type O blood and together they have three children (daughter Frances and son Albert who both have type A blood, and a son Mike with type O blood). Mike marries Johann and together they have one daughter, Guinevere. Guinevere knows that her parents both have the same blood type,…arrow_forward

- 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.

After doing the Punnett squares, write down the possibilities of the offspring’s blood type.arrow_forwardThe teacher suggested that the students revise their model to represent individuals who have a heterozygous genotype and are therefore carriers for the disease.
