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.
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
Genetic drift. This phenomenon is characterized by random changes in allele frequencies within a population due to chance events, such as natural disasters or population bottlenecks, especially in small populations.
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.
Gene flow would increase between the two halves, and speciation would not occur
No, achondroplasia is not caused by nondisjunction. Achondroplasia is a genetic disorder caused by a spontaneous mutation in a gene involved in bone growth. Nondisjunction is a genetic event that occurs during cell division and can lead to abnormal chromosome numbers in offspring.

Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
An allele frequency changes in a population.
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).
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
Adjusting frequency refers to changing the number of occurrences of a repeating event within a specific time period. Increasing frequency generally makes the event happen more often, while decreasing frequency means it occurs less frequently. In the context of electronics, adjusting frequency can impact the performance of circuits and devices, such as changing the pitch of sound waves in audio equipment.
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.
The relative frequency is an estimate of the probability of an event.
Frequency determines the number of times an event is repeated in a unit time. Event could be anything in general.
An insertion/deletion event.
The frequency of occurrence of an event type can vary depending on numerous factors, such as the nature of the event, the environment in which it occurs, and any underlying causes or triggers. Statistical analysis and data collection over time can help determine the frequency of the event type.
