Suppose that in a species of mouse, the gene for brown coat color is dominant over the color black. Another gene (C) is responsible for depositing color on the hair. A single dominant allele (C) is sufficient for the color (black or brown) to be deposited on the hairs; those without a copy of the dominant allele are albino. A female mouse homozygous recessive for both characters is crossed with a male mouse heterozygous for both characters. A) Give the phenotypic ratio of the progeny of F1. (Punnet grid if possible) B) What proportion of the offspring of the F1 will have the same genotype as either of its parents?

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.
