QUESTION 1 Crosses between a pure-breeding strain of white beet plants and a pure-breeding strain of yellow beet plants produced all white beet plants. The F1 plants were crossed to each other (self-cross) and the following F2 plants were observed: 95 white beer plants, 25 red beet plants and 7 yellow beet plants. How many genes determine beet color? Give the genotype of the parental white beet plant and the yellow beet plant. (Use A for a single gene inheritance, A and B for two gene inheritance and A, B, C for three gene inheritance. Write the genotype using proper notation.) Genotype of P1 white beet plant: Genotype of P1 yellow beet plant: What phenotypic ratio is observed in the F2 progeny? (List the ratio as a complete fraction next to the phenotype). Example: ½ purple D Write the genotypes of the following F2 beet plants. (Write the genotype using proper notation.) Genorype of the F2 white beet Genotype of the F2 red beet: Genotype of the F2 yellow beet:

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.
