Your friend tell you that he has a calico cat that is male even though you have learned that calico cats can only be female. What is the explanation for this?     the calico cat is not really male, your friend is confused.     the calico male is the result of non-disjunction and will have one Barr body     the cat is female and has 3 X chromosomes, hence it looks male     the cat must be colorblind

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.
