A rancher determines that the average amount of wool produced by sheep in her flock is 15 kg per year.  In an attempt to increase the wool production in the flock, she picks 5 male and 5 female sheep with the highest wool production; the average amount of wool produced per sheep by those selected is 25 kg per year.  She interbreeds these selected sheep and finds that the average wool production among the progeny of the selected sheep is 22 kg per year. What is the narrow sense heritability for wool production in this flock?   A. 0.8   B. 0.5   C. 0.7   D. 0.3

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.
