In mice black fur (B) is dominant over white fur (b), Green eyes (G) is dominant over blue eyes (g) and Short tail (S) is dominant over long tail (s). All of these genes are on different chromosomes. You take a mouse that is Bb; Gg; Ss and cross it to one that is Bb; gg; ss. What is the chance that an offspring has black fur green eyes and a short tail? 3/4 1/16 1/2 3/8 1/4 1/8 3/16

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.
