College of Cat Genetics: Part 3
by Patricia Turner


The following questions are based on information contained in Study Unit #2 published in the July/August issue of Cat World.

  1. Why are the expressions Champion's blood and diluting out based upon misconceptions?  Are the characteristics of a kitten inherited in its blood?

  3. It is stated that the cat's coded instructions govern the nature of both the chemical ingredients from which it is made and the nature of the chemical changes in its body during its life.  If the cat develops from a fertilized cell, in which part of the cell are the instructions carried?

  5. Why has the use of the symbol y (denoting the sex-linked colour gene producing the red and tortie varieties) been discontinued?

  7. The gene producing extra toes (polydactylia) is symbolized as Pd.  Is this gene inherited as a recessive or as a dominant and how is this information given in its symbol?
