I'm having trouble understanding what my teacher is looking for. If anyone could please lead me in the right direction it would be much appreciated!! Thank you.

In 1981, a stray black cat with unusual rounded, curled-back ears was adopted by a family in Lakewood, California. Hundreds of descendents of this cat have since been born, and cat fanciers hope to develop the "curl" cat into a show breed. The curl allele is apparently dominant and carried on an autosome. Suppose you owned the first curl cat and wanted to breed it to develop a true-breeding variety. Describe the tests that would determine whether the curl gene is dominant or recessive and whether it is autosomal or sex-linked. How would you prove that your tests are correct? Describe a test to determine if the cat is true-breeding.
