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                 .
