The following pedigree shows the inheritance of a rare genetic disorder. Determine the most likely mode of inheritance, and for exam practice (unmarked on the assignment) write a clear justification for your conclusion. Remember that some pedigrees don't provide sufficient data/information to discriminate between possibilities. If that is the case, select all the possible answers.

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.
