You are a fancy rat breeder investigating different characters in fancy rats.  You have two true breeding populations of rats.  One population's fur color is all brown.  The other population;'s fur color is all black.  You breed members of the brown population to members of the black population to get an F1 generation.  The F1 generation grows up, you find they are all brown.  You breed members of the F1 generation to other members of the F1 generation to get an F2 generation.  When the F2 generation grows up, ~75% if them are brown, and ~25% of them are black.  Statistically significant numbers of rat pups were produced in each cross. 1. Give the phenotype and genotype ratio of the F1 generation 2. Give the phenotype and genotype ration of the f2 generation

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.
