You are given a pea that produces round, yellow seeds (both dominant traits), but its genotype is unknown. You conduct a testcross to determine the genotype at both loci, and find that the offspring have the following ratios of phenotypes: % round, yellow, % round, green, % wrinkled, yellow, % wrinkled, green 1. What are all the possible genotypes of a round, yellow pea? Assume shape is controlled by the R locus, and color is controlled by the Y locus. 2. Break this down to the single gene level by answering the following questions: a. What is the proportion of round to wrinkled offspring? b. What is the proportion of yellow to green offspring?

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.
