Mendel is growing flowers. Pure red flowers have a pair of R genes. Pure white flowers have a pair of w genes. Red is dominant to white. (a) Write the Punnett square with a pure red parent cross-fertilized with a pure white parent.

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.
