HITCHHIKER'S THUMB: The distal (last) joint of the thumb can be bent back to form a 45 degree angle with the proximal joint (attached to your hand) if you are homozygous recessive (hh) for this trait. Michael has a well-developed hitchhikers thumb, but neither of his parents show the trait. If his parents have another child, what is the probability that he/she will also have a hitchhikers thumb?

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.
