A(n) is a change in the nucleotide sequence of dna. a(n) is an alternative version of a gene. a(n) is a group of individuals of the same species living in the same area that interact with each other. the total collection of alleles in a population at a given time is the population's . changes in allele frequencies in a population over time is

1) mutation, 2) allele, 3) population, 4) gene pool, 5) microevolution

Explanation:

A mutation is a change in the nucleotide sequence of DNA.

A mutation is a change in DNA sequence, caused by mistakes when the DNA is copied during replication or as the result of environmental factors such as UV light. The result is a change in one base that results in the substitution of one amino acid for another. This is because the genetic code stablish a set of rules used to translate information encoded within the DNA sequence into proteins. Three bases indicates which amino acid will be produced, if one or more of those change, another amino acid may be produced.

An allele is an alternative version of a gene.

Genes of diploid organisms have two alleles, a dominant allele and a recessive allele. So alleles are different forms of a gene. A gene is a region of  DNA that controls a specific trait. If an organism is heterozygous for a certain trait then the dominant trait is expressed. If an organism is homozygous dominant, it means it carries two copies of the dominant allele. While if it is homozygous recessive, if means it carries two copies of the recessive allele.

A population is a group of individuals of the same species living in the same area that interact with each other.

A population is a group of organisms of the same species and that are able of interbreeding and live in a specific area at the same time. These can be people, animals, plants, insects, or bacteria, in general any group of living beings are considered as such.

The total collection of alleles in a population at a given time is the population's gene pool.

Gene pool usually involves a particular species within a population and it refers to the total number of genes of every individual in a population. The collection of genes in a population includes each gene at a certain frequency in relation to its alleles.

A high genetic diversity is due to a large gene pool, which means increased chances of biological fitness, and survival.

Changes in allele frequencies in a population over time is microevolution.

Microevolution refers to changes in allele frequencies which indicates small evolutionary changes within a species or population. So microevolution happens on a small scale, within a single population. There many ways in which microevolutionary changes happen, all of them affect directly gene frequencies:

For example, antibiotic resistance is a case of microevolution by natural selection.
