Variation traits are characteristics that can differ among individuals of the same species, such as height, eye color, or blood type. These traits are influenced by genetics and environmental factors, contributing to the diversity seen within a population. Variation traits play a key role in evolution by providing the raw material for natural selection to act upon.
genetic variation
The term that means a variation of traits is "phenotypic variation." This refers to the observable differences in physical and physiological traits among individuals in a population, which can be influenced by genetic factors and environmental conditions. Variations can include differences in height, color, and behavior, and are crucial for the processes of natural selection and evolution.
Variation under domestication refers to the diversity in traits of domesticated animals or plants resulting from selective breeding by humans. Variation under nature refers to the diversity in traits of wild organisms shaped by natural selection and evolutionary processes in their natural habitats.
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.

genetic variation
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.

Heritable variation refers to differences in traits or characteristics among individuals that are passed down from one generation to the next through genetic mechanisms. These variations are inherited from parents and contribute to the overall genetic diversity within a population.

Variation and competition are the basis of natural selection.When a population of organisms has variety (big/small, fast/slower, etc), and there is competition, then some of those traits will assist in winning the competition, and some will not, which will tend to mean the difference between an organism surviving versus not surviving, which in a large population will mean passing the genes for those advantageous traits on, which then means that those traits have been 'selected' for by the natural act of competition, thus 'natural selection'.
A trait is a specific characteristic or feature of an organism, such as eye color or height. Variation refers to the differences in traits within a population, which can be caused by genetic factors or environmental influences. In other words, traits are the specific manifestations, while variation describes the range or diversity of those traits among individuals.
