Corn breeders obtained pure lines whose kernels turn sun red, pink, scarlet, or orange when exposed to sunlight (normal kernels remain yellow in sunlight). Some crosses between these lines produced the following results. The phenotypes are abbreviated O, orange; P, pink; Sc, scarlet; and SR, sun red.PhenotypesCross Parents F1 F21 SR × P all SR 66 SR: 20 P2 O × SR all SR 998 SR: 314 O3 O × P all O 1300 O: 429 P4 O × Sc all Y 182 Y:80 O:58 ScAnalyze the results of each cross, and provide a unifying hypothesis to account for all the results.

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.
