b. The fourth child tests as having blood type O, which is not possible given the parental genotypes. Look at Figure
c. What is the name of the genetic phenomenon producing this observation?

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?

- Help me create a pedigree of this information: Pedigree analysis: Generation 1: Normal parents (AA x AA) Generation 2: Carrier parents (AA x AS) Generation 3: Affected child (AS x AS) Generation 4: Affected grandchild (SS) This pedigree has two normal parents in the first generation. Second generation carriers carry the sickle cell trait from one parent. The disease is 25% more likely to be inherited in the third generation if both parents have the 'S' allele. If both parents have the 'S' allele, their children will have sickle cell anemia in the fourth generationarrow_forwardA man with type B blood marries a woman with type A blood. They have the first child with blood type O. a. What are the genotypes of the father and the mother? b. What is the genotype and phenotype of the baby?arrow_forwardA new nurse at the hospital has made a terrible mistake. When she bathed three children, she removed their wristbands and does not know which baby is which. The first baby has blood type AB, the second has blood type B and the third has blood type O. She looks up the records of the children and sees that the Jones parents have type A and type B blood, the Smith parents have type O blood, and the Johnson parents have type AB and type O blood. Whose baby is whose? Explain your reasoning.arrow_forward

What blood types will their children be and in what proportion?arrow_forwardConstruct pedigree charts using the inheritance of hemophilia in figure 92 (page 113). This is X-linked inheritance so you are required to label XX for females and XY for males.
