Hannah (with 2 n's) decided to expand on Ana's work by fencing a well isolated plot and deliberately planted 25 red plants and 25 pink plants to allow them to randomly cross. In the F1 generation she observed 115 red, 73 purple and 12 white flowered plants. Do a Chi square test to see if this is expected by random mating with a significance level of P <0.05. Show your work including calculations, the table, the Chi square value, the degrees of freedom used, and your conclusion.

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.
