A strawberry farmer determines that the average weight of individualstrawberries produced by plants in his garden is 2 g. He selects the 10plants that produce the largest strawberries; the average weight of strawberries produced by these selected plants is 6 g. He interbreedsthese selected plants. The progeny of these selected plants producestrawberries that weigh an average of 5 g. If the farmer were to selectplants that produce strawberries with an average weight of 4 g, whatwould be the predicted weight of strawberries produced by the progenyof those selected plants?

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.
