Quality traits, such as fat marbling and milk production are usually the most heritable.
In general quality traits are more heritable than growth traits (such as weight), which are more heritable than reproductive traits (such as conception rate).
Mutation
A gene is a unit that determines heritable characteristics. An allele is one of the alternative versions of a gene for a character.
genes
The word inherited means that it is passed down through the genes from parent to child.
Yes. In 1989, there was a deer which was unable to escape its predator. It died before it got to reproduce. Any unique heritable traits that it might have had were therfore selected out of the population.

First, he had no idea how heritable traits pass from one generation to the next. Second, although variation in heritable traits was central to Darwin's theory, he had no idea how that variation appeared.

Heritability is the proportion of Phenotypic variation in a population that is attributable to genetic variation among individuals. Phenotypic variation among individuals may be due to genetic and/or enviromental factors. Heritability analyses estimate the relative contributions of differences in genetic and non-genetic factors to the total phenotypic variance in a population.
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.
Non- Inherited characteristics are not developed at birth. You learn them in life for example: Riding a bicycle, using a computer, Liking a sport, adding and subtracting, to speak one or more languages. Hope this helps :)
One of the strongest reasons he had for thinking natural selection was the driving force of evolution in fact he started his book with this concept, was artificial selection. Breeders had long know that traits were heritable and they could select for the traits they wanted by just mating the favored organisms. From this example Darwin knew that acquired traits were neither heritable or selectable.
