Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.

I think this is what you're asking.
Examples of Inherited Traits:
Attached or Free Earlobe. If you look closely at your earlobe, it might be a smooth line, or slightly dangly (free).
Allergies. The most common one I think is gluten.
Bone marrow aspiration symptom alerts the health care provider that this child might have acute lymphoblastic leukemia (all)
- Acute lymphocytic leukemia (ALL) is a kind of blood and bone marrow malignancy. Blood cells are generated in the spongy tissue inside the bones.
- Acute lymphocytic leukemia gets its name from the fact that it advances quickly and produces immature blood cells rather than mature ones.
- Acute lymphoblastic leukemia in children is more frequent than other cancers, however it is curable in a significant portion of cases. Adult survival rates are lower, although they are rising.
- ALL has a 5-year relative survival rate of 68.8%. 90 percent of children and 30 to 40 percent of adults are included in the statistics, respectively.

Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
