Riann and Raul are soon-to-be biological parents who are both brown-haired, which reflects a dominant trait. One carries a recessive gene for red hair, while the other does not. What are the chances of Riann and Raul having a red- haired child? If the recessive gene and the dominant gene are paired, the child will have red hair. In this case, the child will not have red hair in any combination. If Riann, the mother, passes on the recessive gene, the child will have red hair. If Raul, the father, passes on the recessive gene, the child will have red hair.

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.
