  4. What is a trait?______
  5. Genes occupy a specific location on a ______.
  6. ______are various forms of the same gene. (Blue eyes b, and Brown eyes B).

  1. Is it possible for two curly tailed pigs to have offspring with straight tails? Show why or why not by creating a

Punnett Square.

Patrick recently married Patti, a cute girl he met at a local dance. He is considered hybrid for his brown eyes. Patti has beautiful blue eyes. Answer the following questions about Patrick and Patti.
