Purebred wrinkled, green-seeded pea plants were crossed with purebred round, yellow-seeded plants. The F1, all of which had round and yellow seeds, were then self-crossed resulting in the following F2: 172 plants with round and yellow seeds, 55 plants with round and green seeds, 58 plants with wrinkled and yellow seeds, and 15 plants with wrinkled and green seeds. Calculate the chi-square value and determine the p-value range. Which of the following are the correct chi-square values, p-value range, and whether you would accept or reject the hypothesis that these results are consistent with Mendelian predictions?

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.
