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.

How are the word parts poly- and genic related to the meaning of the term polygenic traits?
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.
What are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
Gene frequencies in a gene pool may shift randomly and by chance This is called?
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.
Does genetic drift lead to evolution?
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.
Species drift to form a new species?
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.
Who discovered genic balance theory?
Genic balance theory is discovered by american scientist Calvin Blackman Bridges
How is noogenic pronounced?
No-woe-genic. It should be spelled noögenic. The dieresis indicates that consecutive vowels belong to different syllables, as in coöperate ( "co-woppa-rate").
What does the suffix GENIC mean?
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.

Are the suffixes -gen and -genic from German or Latin or Greek?
They are Greek. γενής (-genēs) (producer, lit. begetter).
What is the medical terminology combining form meaning producing?
-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.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
