In 1981, a stray black catwith unusual rounded,curled-back ears was adoptedby a family in California.Hundreds of descendants ofthe cat have since been born,and cat fanciers hope to develop the curl cat into a showbreed. Suppose you ownedthe first curl cat and wantedto develop a true-breeding variety. How would you determinewhether the curl allele is dominant or recessive? How wouldyou obtain true-breeding curl cats? How could you be sure theyare true-breeding?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
