A female hamster from a true-breeding big-eared strain was crossed to a male hamster from a true-breeding short-whiskered strain. Their offspring(F1) had normal ear size and whisker legnth.  1. One of the F1 males was crossed to a true-breeding big-eared, short-whiskered female. the following progeny were obtained. Are the loci regulating ear size and whisker lenght linked, and if so, what is the map distance between them?  Normal ear, normal-whiskers  6 Big-eared, normal-whiskers  22 normal eared, short-whiskers  17 big-eared, shor-whiskers 5 2. Assume that the genes controlling ear size and whisker length are linked and have a map distance of 40cM. What would be the frequency of normal ear, short-whiskered hamsters among the progeny from a testcross of an F1 female?  a. 0.4 b. 0.2  c. 0.3 d. 0.5 e. 0.1

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.
