The Labrador Retriever’s coat colours are black, yellow, and chocolate. Yellow is produced by the presence of a recessive epistatic gene, which has the effect of masking the black and chocolate colour genes. Black (B) is dominant to chocolate (b). Therefore, the possible genotypes and corresponding phenotypes are: Phenotype Possible Genotypes Black G__B__ Brown G__bb Yellow gg__ Predict the percentage of offspring that would be black in colour for each of the following crosses.

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.
