How does natural slection affect the allele frequency in a gene pool?

It changes it by, generally, selecting out some alleles thus allowing other alleles to increase their numbers in the populations gene pool.

What is an example of allele frequency?
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
What question did Hardy and Weinberg want to answer?
To determine how allele frequency changes
What Is the percentage of a particular allele in a population?
Allele frequency.
What is the Random change in a populations allele frequency is known?
Random change in allele frequency is called genetic drift.
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
What effect does natural selection have on the allele frequency of a population?
In the next generation that trait increases in frequency above the frequency in the current generation.
Is it likely to find natural population in hardy-weinberg equilibrium?
Allele frequency is stable
What is an example of allele frequency?
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
The number of times an allele occurs in a gene pool?
Think frequent. More of the allele in the populations gene pool and there is a change in the alleles frequency. Some goes for less of the allele.
If an allele makes up one half of the frequency of a populations allele for a given trait it's allele frequency is?
its not anything.
The change in allele frequency?
Random change in allele frequency is called genetic drift.
What does natural selection cause in a population on a genetic level?
Change in the allele frequency within the gene pool. ?
What question did Hardy and Weinberg want to answer?
To determine how allele frequency changes
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
What effect does natural selection have on the frequency of a recessive lethal allele?
Perhaps not much as the recessive allele is masked in heterozygous condition. Depends on penetration and expresivity of the lethal allele, but any homozygous expression is fatal, so one can expect negative frequency selection; the freqiency is kept low by selection.
What Is the percentage of a particular allele in a population?
Allele frequency.
What happens when a population is in hardy weinberg equillibrium?
In Hardy-Weinberg equilibrium, allele frequencies in a population remain constant from generation to generation. This means that the population is not evolving. Factors such as no mutation, no gene flow, random mating, large population size, and no natural selection contribute to Hardy-Weinberg equilibrium.
