1) Mutation * Replication error * Change in DNA sequence: * ** A) Harmful ** B) Benign ** C) Beneficial (rare) 2) Migration * Movement from one population to another * ** success depends on ability to survive and breed * Gamete transport * Gene flow-reduce number of differences in populations 3) Genetic drift * Loss of alleles * ** maybe result of drastic event * Isolation * Founder Effect * ** one or few individuals carrying alleles ** those individuals interbreed * Bottleneck Effect * ** loss of alleles: less genetic variability 4) Nonrandom mating: increases homozygotes in population 5) Selection: survival of the fittest

What is the method to calculate allele frequencies for a specific gene in a population?
To calculate allele frequencies for a specific gene in a population, you can use the formula: allele frequency (number of copies of a specific allele) / (total number of alleles in the population). This helps determine how common a particular allele is within the population.

allele frequencies
If the actual allele frequencies in a population do not match genotype frequencies predicted by the Hardy Weinberg equation what is the population?
The population is evolving.
A population in which allele frequencies do not change from generation to generation is said to be in?
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
What is the process called when allele frequencies in a population of a species change over time?
Evolution; the change in allele frequencies over time in a population of organisms.
What does it mean for a population to be in genetic equilibrium?
A population is in genetic equilibrium when allele frequencies remain constant over generations, indicating that there is no evolution occurring. This suggests that the population is not experiencing any genetic drift, gene flow, mutations, or natural selection.
What is the type of equilibrium that occurs when allele frequencies do not change?
The type of equilibrium where allele frequencies do not change is called Hardy-Weinberg equilibrium. This equilibrium occurs in an idealized population where certain assumptions are met, such as random mating, no mutation, no migration, no natural selection, and a large population size. In Hardy-Weinberg equilibrium, the genotype frequencies can be predicted using the allele frequencies.
Do Stable allele frequencies prevent microevolution?
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.
Which evolutionary mechanisms could affect allele frequencies in a population being maintained in captivity?
Genetic drift, selection pressures imposed by captivity conditions, inbreeding, and genetic bottlenecks due to small population sizes are some evolutionary mechanisms that can affect allele frequencies in a population being maintained in captivity. These factors can lead to changes in the genetic diversity of the population over time.
What are allele frequencies used for?
Allele frequencies are used to study genetic variation within a population. They can provide information about the genetic diversity, evolution, and potential for certain traits or diseases in a population. By tracking changes in allele frequencies over time, researchers can gain insights into how populations evolve and adapt to their environments.
