Cattle traits means, the characteristics that cattle posses. These traits are what cattle are known for or why the produce the way that they do. For example, Texas longhorns are known for their horn size, this is a trait. Holsteins are known for high milk production, this is also a trait.
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
a phenotype with the greatest frequency in a trait is enviromental conditions. (G00D !-U<K)
The Polled (Hornless) trait is caused by a dominant allele in domestic cattle. From the standpoint of many breeders the trait is a very favorable one, eliminating the need for dehorning andresulting in fewer injuries when new cattle are mixed into a herd. In cattle (even domestic varieties) that have to fend for themselves on the open range/in the wild, hornless cattle could be at a distinct disadvantage if they need to defend themselves from predators. A hornless bull, in the wild would be at a distinct disadvantage in a fight for dominance and the right to breed if the other male has horns.

No, poor is an economic situation. It has nothing to do with a person's character.

socialism.
It depends on what trait is being selected for. Whatever that trait is, it has to be a trait that will improve the BB breed, not unimprove it. How that works is that purebred cattle are selected for a dominant desirable trait and bred together to produce more cattle with that trait. Any other cattle that have the recessive undesirable trait are culled.
Hornless cattle can be helpful because they pose less risk of injury to other animals and handlers. However, they may also be more vulnerable to predators and have limited defense mechanisms in some environments.
