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 generation
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?

- 4:33 4 Alger Edit Today 4:31 PM O LIVE 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.arrow_forwardA man with type B blood marries a woman with type A blood. They have the first child with blood type O. a.

- Construct 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. The gene responsible for the trait is represented by the superscript which should be specified in the legend.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_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.
