What event will increase the frequency of a mutation in a population over time?

Mutation is the alteration of the nucleotide sequence of an organism, virus, or gene. A mutation can be caused by many factors like radiation and chemical exposure, inadequate nutrition, drastic changes in the environment, or an error in DNA replication. The frequency of occurrence of a particular mutation in the gene pool can be affected by drift, natural selection, sexual selection.

A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
Which event best indicates that evolution is still taking place?
Mutation in fruit flies
When chance changes in the gene pool of a small population is know as?
This is the evolutionary process known as genetic drift.
What event occurs in an organism when a chromosome is not copied correctly during meiosis?
a mutation can happen.
One consequence of genetic drift is?
Genetic drift usually only has effect on the genetic diversity of small populations of a species. Often times, genetic drift can greatly reduce the diversity of a population if a significant percent of members of the population leave by a chance event (as opposed to natural selection.) This means that their alleles for various genes leave with them. Genetic drift does not always effect genetic diversity. Most of the time, it is the allele frequency that is affected by genetic drift. For example, if there are 60 long-finned bass and 40 short-finned bass living in a pond, the gene frequency ratio is 3:2. If 25 short-finned are fished out, the allele frequency is now 4:1. If all or most of the members of a population carrying a specific gene were removed from the population because of genetic drift, that would effect the genetic diversity.
A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
What are the major types of mutation event?
gene mutation, chromosomal abberations
What is the Difference in relative frequency and percentage frequency?
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
Which event describes a change where evolution has happened?
An allele frequency changes in a population.
What is the meaning of a relative frequency of 0?
Relative frequency of an event is the frequency of that event divided by the total number of observations. Therefore, a relative frequency of 0 implies the event has zero proportion (or probability).
Relative frequency formula?
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
If a coin is flipped 5 times and a head comes up 3 times what is the relative frequency of a head coming up?
A frequency count is a measure of the number of times that an event occurs. To compute relative frequency, one obtains a frequency count for the total population and a frequency count for a subgroup of the population. ... Thus, a relative frequency of 0.50 is equivalent to a percentage of 50%. 0.60 or 60 percent.
What does frequency?
Frequency determines the number of times an event is repeated in a unit time. Event could be anything in general.
Relationship between relative frequency and probability of an event?
The relative frequency is an estimate of the probability of an event.
What event initiated the enormous increase in human population about 200 years ago?
Migration from one place to another promoted intermarriages that led to increase in population. Availability of food and other resources also led to population increase.
What would produce a frameshift mutation?
An insertion/deletion event.
What is frequency in physics?
Frequency is the number of occurences of a repeating event per unit time
