Genetic drift is change in allele frequencies due to random chance events.
Two types are the Founder effect and the Bottleneck effect.
The founder effect is when a subset of a population goes to a new are where there are no other of that same species.
The bottleneck effect is when a large population is reduced to a small population.
Genetic drift decreases variation in a population and has a greater effect on a smaller population than a larger one.
The word part poly- means "many," and genic refers to genes. Polygenic traits are determined by multiple genes, each contributing a small effect to the overall trait. So, the terms poly- and genic in polygenic traits indicate that multiple genes are involved in determining the trait.
Random changes in allele frequency are due to genetic drift.
Genetic drift. It refers to the random fluctuation of gene frequencies in a population due to chance events, particularly in small populations. It can lead to the loss of genetic diversity and the fixation of certain alleles over time.
Yes. Genetic drift-- the change in allelic frequencies of a population due to chance-- can play a major role in evolution. The effects of drift are most pronounced in small, isolated populations. Drift can bring alleles to fixation very quickly in such populations, and can lead to genetic differentiation between them, possibly contributing to speciation.
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.

No-woe-genic. It should be spelled noögenic. The dieresis indicates that consecutive vowels belong to different syllables, as in coöperate ( "co-woppa-rate").
The suffix "genic" means related to producing or generating. It is often used in scientific terminology to describe something that is involved in the production of a particular substance or process.

They are Greek. γενής (-genēs) (producer, lit. begetter).
-genic is the medical terminology suffix meaning producing.
It is one that causes a disease or, in a few cases, a disorder. Pathos = Ill. Genic = origin.
