In rabbits the dominant allele B produces a black coat color and the recessive genotype bb produces a brown coat.  Body fat color in rabbits is white if a dominant allele Y is present and yellow if the genotype is yy. Assume the mating between rabbits with the following genotypes :​ BBYY x bbyy produces BbYy ​ Calculate the recombination frequency if the BbYy offspring are mated back to brown rabbits having yellow fat bbyy and the following ratio of phenotypes is observed:  Coat color​ Fat color​ # Observed​ Black​ White​ 125​ Black​ Yellow​ 75​ Brown​ White​ 85​ Brown​ Yellow​ 115​

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.
