  • Slide 7
  • 6) What are chromosomes 1-22 referred as?
  • Slide 8
  • 7) Two part question: a)Are men or women more likely to inherit sex- linked disorders b)who do they usually inherit the disorder from?
  • Slide 9
  • 8) Steve is a normal pigmented man with no history of albinism in his family, and he marries Anne, an albino woman. Albinism is an autosomal recessive disorder. Steve and Anne have a child. What is the probability that child will be an albino? (Hint: Draw a Punnett Square if it would help.)

  • 9) Three part question: a)What does a shape with a dot in the middle signify? b)What is the genotype of this person assuming autosomal recessive inheritance? c)What is the genotype of this person assuming sex-linked inheritance?
  • Slide 11
  • 10) Harry is color blind, which is a sex- linked disorder. He married Ginny who is not color blind but whose father was color blind. What is the probability their first born son will be color blind? (Hint: Use a Punnett Square or pedigree to help figure out.)
  • Slide 12
  • 11) Alternative versions of genes are called?

  • 12) If you flip a coin: a. What is the probability of getting heads? b. What is the probability of getting HEADS four times in a row?
  • Slide 14
  • 13) Aicardi Syndrome is a dominant disorder found on the X chromosome of males and females. Michelle is heterozygous for Aicardi syndrome, but her husband Jerry is completely healthy. List the genotypes in the F1 generation. (Use a Punnett Square.)
  • Slide 15
  • 14) Selena is a carrier of PKU. Her parents were also both carriers of this recessive disorder. She marries Justin, who is heterozgyous for PKU. They have three kids, two boys and a girl. Their daughter has been showing signs of PKU. Draw a pedigree of their family, including genotypes. 2 Unknowns
  • Slide 16
  • 15) Fill in the missing genotype and explain how you know.
  • Slide 17
  • 16) Write out the two types of genotypes a male can have when referring to sex-linked disorders. (Use the letter H.)
  • Slide 18
  • 17) What is the genotype of the child, assuming sex-linked inheritance?
  • Slide 19
  • 18) Where was Gregor Mendel from and what was his profession?
  • Slide 20
  • 19) Huntingtons Disease is an autosomal dominant disorder. Kelly had Huntingtons disease and before she died at the age of 38, she married and had 2 kids. Her husband, Fred, was completely healthy. What are the chances that both her children will be born with Huntingtons disease? (Hint: Use a Punnett Square if needed to solve.)
