  2. All changes in genes are called _______.

  3. mutations

  4. The failure of chromosomes to separate properly is called ______.

  5. nondisjunction

  6. A mutation that occurs in the cells that produce the sex cells

  7. Germ mutation

  8. The type of mutation that occurs when a section of a chromosome reverses direction

  9. inversion

  10. When homologous chromosomes exchange part of their DNA

  11. Crossing-over

  12. The typical human female has what genotype?

  13. XX

  14. A male fruit fly has what genotype?

  15. XY

  16. The ratio of male fruit flies to females is about what?

  17. 1:2or50%

  18. Recessive sex-linked traits usually are seen in what group of people?

  19. males

  20. When is a recessive sex-linked trait seen in females?

  21. When the female has that recessive trait on both X chromosomes.

  22. Why is hemophilia more common in males?

  23. It is sex-linked recessive and males only have one version of the gene

  24. A female who is not colorblind, but has one of the recessive allele for colorblindness, is called a

  25. carrier

  33. ABABO

  34. A person who has all the following antigens;A , B, Rh

  35. AB+

  36. A person who has none of the following antigens;A , B, Rh

  37. O-

  38. Rh is determined by several genes. What do we call this?

  39. Polygenic

  40. What type of inheritance is shown in blood group determination?

  41. Codominance
