You start a cross with a true-breeding red-eyed troll and a true-breeding white-eyed troll, and then cross the F1 offspring to make the F2 generation.  In the F2 generation, you collect 3 red-eyed trolls, 8 white-eyed trolls, and 5 pink-eyed trolls.  Use a chi-square test to evaluate whether the data matches your expectation if the trait is controlled by a single gene with incomplete dominance.     In the spaces below, enter the expected number of offspring in each phenotypic group that you would use to calculate your chi square.  Report your expected values to the nearest 0.01. Expected Number of Pink-eyed trolls  Expected Number of Red-eyed trolls  Expected Number of White-eyed trolls    Calculate your chi-square test and answer the following questions: How many degrees of freedom do you have in this test  Do you reject the null hypothesis?  Yes or no?

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.
