Types of genetic drift?
There are two main types of genetic drift: population bottleneck and founder effect. Population bottleneck occurs when a population's size is drastically reduced, leading to a loss of genetic diversity. Founder effect occurs when a small group of individuals establishes a new population with limited genetic variation.
How does genetic drift impact small populations and why is it particularly significant in their genetic diversity?
Genetic drift is the random change in gene frequencies that occurs in small populations. In small populations, genetic drift can have a big impact because there are fewer individuals to pass on their genes, leading to a greater chance of losing genetic diversity. This can result in a decrease in genetic variation and increase the risk of inbreeding, which can lead to negative effects on the population's health and survival.
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.
How does genetic drift occur?
Genetic drift occurs when random events cause certain alleles to become more or less common in a population. This can happen due to factors like population bottlenecks or the founder effect, where a small group of individuals carries a subset of the genetic diversity of the larger population. Over time, genetic drift can lead to changes in allele frequencies and reduce genetic variation within a population.
When is genetic drift likely to occur?
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.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
What is it called when evolution that occurs as a result of chance events like catastrophe?
genetic drift
Is genetic drift of product of genetic change?
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.

Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.

What small genetic change such as a single mutation may result in?
genetic drift....
What causes genetic drift?
Genetic drift is caused by random sampling errors in a population's gene pool. These errors can occur during processes like genetic recombination, migration, or founder events, leading to changes in allele frequencies over generations. The smaller the population, the greater the impact of genetic drift.

Is Natural selection is the only mechanisim whereby evolution occurs?
No, there is genetic drift and gene flow between populations to consider.
When is genetic drift likely to occur?
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.
