Mendel crossed true-breeding plants with wrinkled and green peas to true breeding plants with round and yellow peas. Then he crossed the Fl plants to true-breeding plants with wrinkled, green peas and observed in the progeny 31 plants with round, yellow peas, 26 plants with round, green peas, 27 plants with wrinkled, yellow peas, and 26 with wrinkled, green peas. a) What proportion of these four phenotypes would be expected? b) Calculate the appropriate chi-square and determine if it is consistent with Mendelian expectations (be sure to indicate the probability range).

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.
