You've been having trouble sleeping because of your obsession with understanding the Rh factor (+ positive or - negative) in blood typing. Your blood type is O-. You know both of your parents phenotypes so you decide to visit a famous genetic counselor, Dr. Jean Etix. After she bills you $300, she tells you to take your parents' genotypes and "stick them in a punnet square!" Your Dad is B- and your Mom is A+. What are their possible genotypic combinations? Bi ++ and IAi +- Bi +- and IAi +- Bi +- and IAA +- BIB +- and lAi +- O Bi -- and 1Ai+-

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.
