What flood kills most of a population of ants that live near a river. After the flood the ant population increases but its allele frequency is different. What type of effect is this?

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.
The number of trout in a lake drops when the lake is polluted. The trout population increases but the allele frequency is different than it was before the pollution. What type of effect is this?
Apex . . bottleneck
What Is the percentage of a particular allele in a population?
Allele frequency.
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 is meant by the allele frequency?
An allele frequency measures how common certain alleles are in the population. "The distribution of alleles in a population" -Apex
What is allele fixation?
An allele present in all members of a population
What happens when a population is in hardy wienberg equilibrium?
Allele frequency is stable The phenotype frequency does not change.
How is evolution different?
Different from what? Evolution is the change in allele frequency over time in a population of organisms. So, I repeat, what difference?
What effect does a bottleneck have on the allele frequency of a population?
A bottleneck can lead to a significant reduction in the genetic diversity of a population, causing certain alleles to be lost and others to become more common. This can increase the frequency of rare alleles and result in genetic drift, potentially leading to an increase in genetic diseases or reduced fitness in the population.
What is meant allele frequency?
How often a certain allele (or trait) occurs in a certain population.
Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
Could you define Minor and major allele frequency?
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
