In mice there are two loci responsible for coat color:      Locus 1B- determines whether hair has bands:       B- results in hair with bands & produces an agouti coat pigment (brown)       b- homozygotes have no bands & their coat pigment is black      Locus 2A- affects enzymes responsible for pigment production:      A- results in normal pigment production      a- homozygotes block all of the pigment production & are albino (white)   What are the possible genotypes & phenotypes of the progeny if you were to cross 2 mice, which are heterozygous for both traits? What type of gene action is being expressed in this example?

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.
