Problem: Suppose you observed 240 progeny that resulted from a monohybrid cross and involved genes that obeyed Mendelian inheritance, how many heterozygous progeny would you expect to observe?
In a test population of 1000 people, 200 display albinism. You hypothesize that this trait follows Mendelian genetics with a 3:1 ratio of non-albinism to albinism. Use theΧ2test to determine whether the data support the hypothesis or not.
Show your steps and explain your reasoning. Χ2 = Σ [(O - E)2/Ewhere O is the observed number of individuals in a defined class, and E is the expected number of individuals in a defined class based on the hypothesis. The Σ symbol indicates that you should sum the results for each defined class.
