In rabbits, fur colour can be either grey, black or blotchy. Blotchy is present as grey and black spots present in no specific pattern. Males are almost always either grey or black, while females can be grey, black or blotchy. However, a male individual is found that shows the blotchy pattern, and you expect a non-disjunction event might be to blame. Explain the inheritance of coat colour in rabbits, and also provide an explanation for the blotchy male.

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.
