You are evaluating a trait that is associated with fur color in mice. The trait is controlled by a single autosomal gene where A1 codes for dark fur and A2 codes for light fur. You are mating two homozygous parents- a male that is A1A1 and a female that is A2A2. You learn that the trait is involved in genomic imprinting where the paternally inherited allele is heavily methylated to the point where it is completely silenced. If you performed a RECIPROCAL CROSS what phenotypic ration would you predict among the progeny? 100% Dark 100% Light 3Dark:1Light 1Light:3 Dark None of the answers I want are shown.

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.
