Question

Two merged populations eventually have an allele frequency that is the average of the frequencies of that allele in the initial two populations. What would increase the speed with which this happens?

A species is a group of similar animals that can ____________.

Native Americans had never experienced smallpox, measles or influenza before these diseases were introduced into the Americas by infected Europeans. An estimated pre-Contact North American population of approximately 12-15 million was subsequently reduced to less than 2 million. This phenomenon is known as ____________.

The phrase “sampling error” means that __________.

Explanation / Answer

2) A species is a group of similar animals that can mate and reproduce fertile offspring.

It is the biological definition for a 'Species'. Biologically, a species can be defied as a group of individuals that are able to interbreed among themselves and capable of producing fertile offsprings.

3) The phenomenon described here is an example of Population bottleneck.

The phenomenon itself can be defined as an event where the population size is reduced spontaneously. Here, in this example, the population has reduced drastically from 12-15 million to less than 2 million as a result of disease outbreak. This change is obvious and can be referred to as Population Bottleneck.

4) The phrase 'Sampling error' means that, you have a small, unrepresentative sample of a larger population.

Sampling error usually appears in statistics when the sample size is usually smaller as well as when the sample is unrepresentative. For accurate statistical results, always the sample selected should represent the entire population of data.
