  1. Genetics &Heredity

  2. Disorder in which the blood does not clot properly hemophilia

  3. Disease in which there is slow deterioration of brain in middle age; fatal Huntington’s disease

  4. Disease where there is poor blood circulation due to misshapen red blood cells, African heritage Sickle cell anemia

  5. If an individual possesses two recessive alleles for the same trait, the individual is said to be__________________. homozygous

  6. Frosty the snowman is heterozygous for his button nose and homozygous for his coal eyes. Frieda the snow-woman has a carrot nose and pine cone eyes.What are their genotypes?Frosty = _________Frieda = _________

  7. Frosty the snowman is heterozygous for his button nose and homozygous for his coal eyes. Frieda the snow-woman has a carrot nose and pine cone eyes.What are their genotypes?Frosty = BbCCFrieda =bbcc

  8. If a characteristic is sex-linked, it a. occurs most commonly in males. b. occurs only in females. c. can never occur in females. d. is always fatal

  9. If a characteristic is sex-linked, it a. occurs most commonly in males.

  10. The passing of traits from parents to offspring is called heredity

  11. A wealthy couple is killed when their private jet crashes in the Alps. They leave behind an estate of 100 million dollars. Six months after their death a man comes forward claiming he is their long-lost son. The man claiming to be their son has blood type B. The deceased wealthy man is type AB and his wife is type O. You are the judge. Is it even possible that he should inherit $100,000,000?___________ Complete a Punnett square to show why you answered the way you did. (2 points)

  12. YES. O O A B

  13. Cleft Chin is dominant. Non-cleft is recessive.A = cleft a = non-cleftWhat are the genotypes of persons 4, 9, and 15? Darkened shapes do NOT have a cleft chin.

  14. Cleft Chin is dominant. Non-cleft is recessive.A = cleft a = non-cleftWhat are the genotypes of persons 4, 9, and 15? aa aa Aa A? Darkened shapes do NOT have a cleft chin.

  15. The weather turns cold and snowy. A rabbits fur turns white. What type of factor is affecting this characteristic? Environment

  16. The “father” of genetics is _____________________. Gregor Mendel

  17. What inheritance pattern is described when you cross a white cat with a black cat and get a gray cat? Incomplete dominance

  18. Complete the Punnett square and give the phenotypes and their ratios.B = Blue b = pink

  19. Complete the Punnett square and give the phenotypes and their ratios.B = Blue b = pink 3 Blue : 1 Pink

  20. On what chromosome will you usually find a sex-linked trait? X
