Those behaviours that are influenced by heritable factors are subject to natural selection. For most animals, all behaviour is, to some degree, the result of or at least affected by heritable factors.

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).
yes, only heritable changes in the DNA come under the perview of mutation.
A gene is a unit that determines heritable characteristics. An allele is one of the alternative versions of a gene for a character.
Heritable variation is the variation in characteristics caused by genetic factors.

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.

That's correct. Gender differences in heritable personality traits could be influenced by a variety of factors beyond just biological sex, such as socialization, environment, and cultural influences. It's important to consider the complex interplay of these factors when examining gender differences in personality traits.

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.
