In sweet peas, the two allelic pairs (genes) C, c and P, p are known to effect pigment formation in the flowers. The dominants, C&P, are both necessary for colored flowers. Absence of either results in white flowers. A dihybrid plant is crossed to a white one which is heterozygous at the "C" locus. 1. What is the genotype of the dihybrid plant? 2. What is the genotype of the white plant? 3. What kinds of flowers, colored or white, are to be expected from the cross above? Include the ratio. 4. Assume that another gene ,allelic pair, in sweet peas also affects pigment formation in addition to the genes mentioned in above question. The presence of the dominant, R, is required for red flowers. It's recessive allele, r, produces yellow flowers. What would be the phenotypes of the following plants in relation to flower color? 4a.

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.
