In cats, there is a gene that codes for fur colour on the X chromosome. One allele gives black fur, and the other gives orange fur. A cat that has one of each allele (heterozygous) has fur that has large patches of orange and large patches of black. This fur colour is called tortoiseshell (A) a) is this strict Mendelian, incomplete dominance, or co-dominance? (Choose only one and explain) b) is it possible for male cats to have the tortoiseshell fur colour? Explain.  If a female fruit fly homozygous for white eyes is crossed with a red-eyed male, what percentage of the offspring would have white eyes? (eye colour is x-linked and white is recessive) a) 100% b) 0% c) 50%. d) 25%

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.
