What allele frequency in a population do not change or the population does not evolve?
In a population where allele frequencies do not change, it is said to be in Hardy-Weinberg equilibrium. This condition occurs when certain criteria are met: the population is large, mating is random, there are no mutations, no gene flow (migration), and no natural selection. Under these circumstances, the genetic variation remains stable over generations, indicating that the population is not evolving.

Can the bacteria in yogurt evolve over time?
Yes, bacteria in yogurt can evolve over time through natural selection and genetic mutation. Changes in the environment, such as temperature or pH, can lead to the selection of bacteria with beneficial traits that allow them to survive and thrive in their specific conditions. This process can result in the adaptation of the bacterial 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.
What species can evolve from natural selection?
Microevolution is merely evolution, the change in allele frequency over time in a population of organisms, and all animals do this all the time.Natural selection is always summing up the variation among a population of organisms and selecting those that show survivability and reproductive advantages, even is the selection does no more that stabilize the organisms phenotypes.Look to the evolutionary history of horses or whales to see clear examples of evolution and selection through time.
Why must an adaptation be inheritable if it is to cause a population to evolve?
An adaptation must be inheritable in order to be passed down from one generation to the next. If an adaptation is not inheritable, it will not be maintained in the population over time through natural selection, and therefore will not lead to evolution. Inheritability ensures that the adaptive trait can increase in frequency within a population over generations.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
The smallest unit that can evolve is a?
Is a population. Consider the definition of evolution.Evolution is the change in allele frequency over time in a population of organisms.
Will cats continue to evolve?
Evolution is the change in allele frequency over time in a population of organisms. So, cats will continue to evolve. Organisms evolve, or go extinct. Speciation is another thing.
Describe what is occurring when a population is said to evolve?
The allele frequency of the populations gene pool is changing.
Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
Why is population the smallest unit of organism that can evolve?
Evolution is defined as a change in allele frequencies over time. Since individuals have only the set of alleles that they're born with, an individual cannot evolve. This leaves the population as the smallest unit that can evolve.
What is evolition?
it's where a Pokemon has to have a certain item needs a certain move,needs traded, or has to get to certain lv.(level) to change into a similar form.Some Pokemon can evolve more than once(example: turtwig evolves into grotle and grotle evolves into torrterra)but some Pokemon can't evolve(example:groudon,dialga,and ditto)you can stop an evolution by pressing B while they evolve.Hope I helped:):):):):):)
What is the smallest biological unit that can evolve over time?
The smallest biological unit that can evolve over time is a population. Evolution is the change in the heritable characteristics of a population over generations. Individuals do not evolve, but rather the frequency of traits within a population changes over time.
Why can't an individual in a population evolve?
Basically it is because they die and any mutations in germ lines, genetic recombinations and any beneficial variations die with them. Only populations evolve because the frequency of alleles in population gene pools change over time due to the selection of individuals who pass on these frequency changing traits to progeny.
How do bacteria know when enough of them are being destroyed that it's time to attempt to evolve?
They don't! You misunderstand evolution. Say there is a population of bacteria. All this population varies; one from the other. Say the population is attacked by a antibiotic. Most, but not all bacteria die. Those that survive are different in allele frequency from those that died. So, the descendants of these survivors will have the traits that allowed the progenitors to be reproductively successful in the antibiotic environment. Thus allele frequency in changed over time in a population of organisms. Natural selection leading to evolution.No foresight, no planning, no direction and not progressive; just a natural process where small local rules can give rise to change and complexity.
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.
Can the bacteria in yogurt evolve over time?
Yes, bacteria in yogurt can evolve over time through natural selection and genetic mutation. Changes in the environment, such as temperature or pH, can lead to the selection of bacteria with beneficial traits that allow them to survive and thrive in their specific conditions. This process can result in the adaptation of the bacterial population over time.
