In tomatoes, cut leaf and potato leaf are two contrasting traits. Cut leaf (C) is dominant to potato leaf (c). Purple stem and green stem are another pair of contrasting traits. Purple stems (P) are dominant to green stems (p). A true breeding cut, green plant is crossed with a true breeding potato, purple plant. The F1 plants of this cross were allowed to breed. The 320 F2 plants were phenotypically. (shown below). Does this data conform to a 9:3:3:1 ratio? Use ti x^2 (Chi-Square) test to explain your answer.

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.
