Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.

When microevolution occurs what kind of frequencies change?

allele


Do natural and survival ofthe fittest equal evolution?

Natural selection (survival of the fittest) is a key mechanism driving evolution but they are not the same. Evolution encompasses all changes in allele frequencies in a population over time, while natural selection is one process that can lead to those changes by favoring certain traits in individuals that increase their reproductive success.


How can under natural conditions cause allele frequencies to change?

Under natural conditions, allele frequencies can change due to various factors such as genetic drift, gene flow, natural selection, mutation, and non-random mating. These mechanisms can lead to changes in the distribution of alleles within a population over time.


Under ideal conditions how do allele frequencies change over time?

Under ideal conditions, allele frequencies can change over time due to genetic drift, natural selection, gene flow, and mutations. These factors can cause certain alleles to become more or less common in a population, leading to changes in allele frequencies. Over many generations, these changes may result in evolution occurring within the population.


What is a population that changes over time due to natural selection?

A population of organisms that changes over time due to natural selection is called a evolving population. Through natural selection, individuals with traits that are better suited to their environment tend to survive and reproduce, leading to changes in the frequency of traits within the population over generations.

How do alleles influence natural selection?

It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.

What exactly does the concept of microevolution mean?

Microevolution is the changes in allele frequencies due to mutation, natural or artificial selection, gene flow, and genetic drift. These changes occur over a long period of time within a given population.

Natural selection


The work of hardy and weinberg led to what statement about evolution?

The Hardy-Weinberg principle provides a mathematical model to predict genotype frequencies in a population that is not evolving. If genotype frequencies in a population do not match the predicted frequencies, then evolution (such as genetic drift, natural selection, or gene flow) is likely occurring.


Under ideal conditions how do allele frequencies change over time?

Under ideal conditions, allele frequencies can change over time due to genetic drift, natural selection, gene flow, and mutations. These factors can cause certain alleles to become more or less common in a population, leading to changes in allele frequencies. Over many generations, these changes may result in evolution occurring within the population.


What is the main difference between natural selection and genetic drift?

The main difference between natural selection and genetic drift is that natural selection involves the differential survival and reproduction of individuals based on their traits, leading to an increase in advantageous traits in a population over time. Genetic drift, on the other hand, is a random process that can lead to changes in allele frequencies in a population due to chance events, rather than selection pressure.


What causes the allele frequencies to changes?

1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.

The frequencies of alleles and genotypes remain constant from generation to generation unless?

Unless there are factors such as mutation, genetic drift, gene flow, or natural selection that can cause changes in allele frequencies within a population. This concept is known as the Hardy-Weinberg equilibrium, which describes the conditions under which allele and genotype frequencies remain stable over time in a population.
