In rabbits, an allelic series helps to determine coat color: C (full color), cch (chinchilla, gray color), ch (Himalayan, white with black extremities), and c (albino, all-white). The C allele is dominant over all others, cch is dominant over ch and c, ch is dominant over c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C > cch > ch > c. The rabbits in the following list are crossed and produce the progeny shown. Give the genotypes of the parents for each cross: Phenotypes of parents Phenotypes of offspring a. full color × albino 12 full color, 12 albino b. Himalayan × albino 12 Himalayan, 12 albino c. full color × albino 12 full color, 12 chinchilla d. full color × Himalayan 12 full color, 14 Himalayan, 14 albino e. full color × full color 34 full color, 14 albino

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.
