Label the generations and individuals Answer the following questions. 1. Which of these individuals in the pedigree is a male with the genotype aa? a. Individual 1-1 b. Individual II-2 C. Individual III-2 d. Individual III-5 2. Individuals III-6 and III-7 have two little monsters and are expecting a third one. Their two children have two eyes. What is the chance that the third child will have one eye? a. 25% b. 50% C. 75% 100%

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.
