The trait of being hornless can be harmful if the cow is in an area where it may have to defend against predators. If the animal is aggressive, having no horns can be an asset to the handler.

If a hornless bull mates with a horned cow what are the two genotypes of the two parents?
Hornless = polled. Polled cows and bulls can be either homozygous polled or heterozygous polled. So, since we have no idea of what kind of calf they produce, the genotypical cross will look like this: (H = polled and h= horned) H_ x hh "H_" symbolizes the unknown allele that the polled bull has. Is he hetero polled or homozygous polled? The "hh" of the cow symbolizes she is homozygous horned, since the horned trait in cattle is a recessive trait: polled gene is dominant.
How selective breeding using dominant principle can positively affect Belgian Blue Cow?
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.
What is the definition of cattle traits?
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.
What does polled mean for a sheep?
Polled cattle are those that are born without any buds that grow into horns. Instead they have in the middle of the top of their heads a knobby area that is called a poll, thus the reason that hornless cattle are called "polled." Polled is a genetic trait that is used in a lot of cattle today, and is a trait to be taken advantage of when the offspring has a horned sire or dam.

How is Hornless cattle a harmful trait?
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.

What is an observable trait of an organism that can mask a recessive 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
