You are walking to school on a December morning. There is a thin layer of snow on the grass. As you walk, you notice two distinct sets of paw prints left behind by some animals.

Based on this scenario, what kind of relationship do you think the two animals have?       Mutualistic     Commensalistic     Predator-Prey     Ammenalistic

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.
