The problem is : The inheritance patterns of some traits in guinea pigs are listed in the table below. Corn snakes show variety in their skin color pattern. While the complete genetics of corn snake color are complex, the most common colors on normal corn snakes—red and black— are each coded by one gene. For the red gene, the allele for the presence of red pigment (R) is dominant and the allele for the absence of red pigment (r) is recessive. Likewise, for the black gene, the allele for the presence of black pigment (B) is dominant and the allele for the absence of black pigment (b) is recessive. Complete a Punnett square for the cross of two snakes that are heterozygous for the black color. What percentage of the offspring is expected to have black pigment in their skin?

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.
