Bio1151 Chapter 15 The Chromosomal Basis of Inheritance
  1. Mendel's laws can be explained by the               theory of inheritance and production of gametes by           .

  2. Thomas Hunt Morgan's experiments with fruit flies (Drosophila) showed that the eye-color         is sex-linked and located on the      chromosome.

  3. In humans and other mammals, the sex chromosomes      and      determine an organism's gender.

  4. Other forms of sex determination include a                  system used by many social insects.

  5.        -linked disorders exhibit peculiar inheritance patterns.

  6.                   occurs when homologous chromosomes or sister chromatids do not separate normally in meiosis.

  7. A female heterozygous for an X-resident gene may show           phenotype, due to X inactivation.

  8. Chromosome alterations include            ,               ,             , and                 .
