List any phenotypes (e.g., physical or behavioral) that might differ between the average person who is a twin and the average person who is a singleton. Explain your answer (provide an external source, if possible).  For most phenotypes, are twins representative of the general population? Why or why not? Do you think the experience of being an MZ twin is very different from being a DZ twin? In which ways?

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.
