Half the genes a calf gets is from his sire, and the other half from his dam. Some genes will be more dominant than others, depending on which of his parents has the dominant gene, and some, like carcass characteristics from his sire, are more heritable than others. Often a bull that has better genetics than the rest of the cowherd will produce calves that have slightly better genetics than their dams.
Some of the more heritable traits that a bull's offspring can receive from him, if he's better quality than the cowherd, are:
Lean/bone ratio (60% heritability)
Lean percentage (55% heritability)
Mature cow weight (50% heritability)
Carcass grade (45% heritability)
Thickness of outside carcass fat (45% heritability)
Dressing percentage (40% heritability)
Marbling (40% heritability)
Ribeye area (40% heritability)
Yearling weight (feedlot)(40% heritability)
Yearling weight (pasture (35% heritability)
Efficiency of gain (35% heritability)
Birth weight (30% heritability)
Post-weaning gain (30% heritability)
Tenderness (meat quality) (30% heritability)
Carcass weight (25% heritability)
Weaning weight (25% heritability)
Calf survival (10% heritability)
Calving interval (10% heritability)
Calving ease (10% heritability)
The definition of heritability is: "The proportion of the differences among cattle, measured or observed, that is transmitted to the offspring. Heritability varies from 0 to 1. The higher the heritability of a trait, the more accurately does the individual performance predict breeding value and the more rapid should be the response due to selection for that trait."

the answer to this question is traits.
Genetic variability is the tendency of individual genetic characteristics in a population to vary from one another.

Yes, so long as the bull is unrelated to those cows. It is unrecommended to breed a bull to any of his next-of-kin due to genetic abnormality issues that come with inbreeding and line-breeding. Only do this if the breed itself is pure enough to do any inbreeding.

The DNA molecule is the genetic material of life.
All human traits have a genetic component, but characteristics are genetic traits and environmental influence on humans.
Phenotype is the genetic factor that determines the color of a hummingbird. An organism's physical characteristics areincluded in phenotype.
