The coat colour of some dogs is an example of an epistatic interaction. The common alleles are black (B) and brown (b). There is a separate gene on a separate chromosome that influences coat colour; it prevents colour formation and causes a white coat. L = prevents color formation and causes a white coat l = allows colour formation to occur. If a white dog heterozygous for both traits is crossed with a black dog that is heterozygous for the color gene,  which of the following represents the phenotypes of the offspring? Select one:

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.
