A rancher determines that the average amount of wool produced by a sheep in her flock is 22 kg per year. In an attempt to increase the wool production of her flock, the rancher picks the five male and five female sheep that produce the most wool; the average amount of wool produced per sheep by those selected sheep is 30 kg. She interbreeds these selected sheep and finds that the average wool production among their progeny is 28 kg. What is the narrow-sense heritability for wool production among the sheep in the rancher’s flock?

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.
