Radishes may be long, round, or oval, and they may bered, white, or purple. You cross a long, white variety witha round, red one and obtain an oval, purple F1. TheF2 shows nine phenotypic classes as follows: 9 long, red;15 long, purple; 19 oval, red; 32 oval, purple; 8 long,white; 16 round, purple; 8 round, white; 16 oval, white;and 9 round, red.a. Provide a genetic explanation of these results. Besure to define the genotypes and show the constitutionof the parents, the F1, and the F2.b. Predict the genotypic and phenotypic proportionsin the progeny of a cross between a long, purple radishand an oval, purple one.

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.
