In a herd of beef cattle, the average yearling weight of all animals was 800 lb when corrected to a bull basis. Bulls and heifers kept for breeding weighed 1000 and 825 lb, respectively. The progeny of those individuals selected for breeding had an average yearling weight corrected to a bull basis of 845 lb. What is the apparent genetic control of the trait

Explanation:

The trait is genetic and not dependent on environment. When a trait is dependent on the genetic component of the parental generation, the ability of the traits to be passed from a generation to another is high and this will be revealed in their resemblance with the parent. Hence, the case of the offspring with an average weight of 845lb.

If the trait is controlled or influence by the environment there will be a difference when the offspring is produce because until the same environment is given to the offspring the trait cannot be expressed.

plz give me the characteristics.
