Please read the scenario below, and then answer the question (in bold) that follows. In cats, the allele (B) produces a black coat color and the allele (b) produces a yellow coat color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell coat color. The alleles (B) and (b) are also sex-linked (i.e., they are carried on the X chromosome), and cats possess an XX-XY sex determination system, like humans. If a female cat with a tortoise shell coat mated with a male cat who had a yellow coat... What percentage of their offspring will have tortoise shell coats?   a. 0%   b. 25%   c. 50%   d. 75%

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.
