2. Three different pure-breeding strains of corn that produce ears with white kernels were crossed to eachother. In each case, the F1 plants were all red, whileboth red and white kernels were observed in the F2generation in a 9:7 ratio. These results are summarized in the following table.F1 F2white-1 × white-2 red 9 red : 7 whitewhite-1 × white-3 red 9 red : 7 whitewhite-2 × white-3 red 9 red : 7 whitea. How many genes are involved in determiningkernel color in these three strains?b. Define your symbols and show the genotypes for thepure-breeding strains white-1, white-2, and white-3.c. Diagram the cross between white-1 and white-2,showing the genotypes and phenotypes of the F1and F2 progeny. Explain the observed 9:7 ratio.

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.
