If you try to throw a basketball into a basket, the likelihood ofsucceeding depends on the size of the basket. It is more likely thatyou will get the ball into the basket if the basket is bigger. In yourown words, explain how this analogy applies to the idea that thelikelihood of crossing over is greater when two genes are far apartthan when they are close together?

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.
