In Labrador retrievers fur color is controlled by two genes. One gene controls pigment production with the dominant B allele producing a black pigmentation and the recessive b allele a brown pigmentation. The other gene controls the deposition of the pigment in the hair with the dominant E allele producing a functional transport system and the recessive e allele a nonfunctional transport system. Which of the following genotypes belongs to a true-breeding yellow lab, i.e. a lab that always produces yellow offspring when bred with another lab of the same genotype?

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.
