Two genes in tomatoes are 61 mu apart; normal fruit (F) is dominantto fasciated (flattened) fruit ( f ), and normal number of leaves(Lf ) is dominant to leafy (lf ). A true-breeding plant with normalleaves and fruit was crossed to a leafy plant with fasciated fruit.The F1 offspring were then crossed to leafy plants with fasciatedfruit. If this cross produced 600 offspring, what are the expectednumbers of plants in each of the four possible categories: normalleaves, normal fruit; normal leaves, fasciated fruit; leafy, normalfruit; and leafy, fasciated fruit?

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.
