Cats also have a locus (gene) for a character called agouti. In cats with agouti fur, pigment is unevenly distributed (see Fig. 1). The agouti allele is dominant to the allele for regular fur. A male cat who long haired and is heterozygous for agouti fur is crossed with a female who has regular, non-agouti fur and is homozygous for short fur.

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.
