it is passed down from the parents to the offspring
Without genetic diversity, natural selection cannot occur
Genetic drift may occur when a small group of individuals colonizes a new habitat. These individuals may carry alleles in different relative frequencies than did the larger population from which they came.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Radioactive substances in the environment
If something were passed down from parents, that would be inheritance. A mutation is when something goes wrong and causes a change in the genetic structure. Mutations can be caused by radiation or chemicals or mutations can also occur "naturally" when some part of DNA replication or correction goes wrong.
Genetic variation is one of the conditions required for Natural Selection to occur.
No,it does not do any damage to the engine or the drive-train of the vehicle with an automatic transmission
Yes, heredity occurs in viruses through the transmission of genetic material from one generation to the next. Viruses have a simple genetic makeup, usually in the form of DNA or RNA, which allows them to replicate and pass on their genetic information. This genetic material can mutate over time, leading to changes in the virus's characteristics.
The transmission of genetic information from parent to offspring is called genetics or genetic transmission. Such genetic information includes height, eye and hair color.
Vertical transmission in animals does happen. It means a disease, condition or trait is transmitted from one generation to the next. This might be genetic or by contact, e.g. infection passing through the placenta.
Lack of genetic variation within a population. Small population size that restricts gene flow. No mutations that introduce new genetic material. Lack of environmental pressures or changes. High levels of genetic drift that prevent natural selection from acting.
Genetic drift has a larger effect on smaller populations.

Genetic Counselor
Genetic drift is more likely to occur in small populations where chance plays a significant role in determining the frequency of alleles. It can also happen in isolated populations or during population bottlenecks where genetic diversity is reduced.
