7. In the guinea pig, one locus involved in the control of coat color may be occupied by any of four alleles: C (full color), ck (sepia), cº (cream), or c (albino), with an order of dominance of: C> c> cd > c. In the following crosses, determine the parental genotypes and predict the phenotypic ratios that would result. a) Sepia x cream, where both guinea pigs had an albino parent b) Sepia x cream, where the sepia guinea pig had an albino parent and the cream guinea pig had two sepia parents c) Sepia x cream, where the sepia guinea pig had two full color parents and the cream guinea pig had two sepia parents d) Sepia x cream, where the sepia guinea pig had a full color parent and an albino parent and the cream guinea pig had two full color 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.
