If this happens then Natural Selection occurs because Natural Selection is the increase or decrease in allele frequencies due to the impact of the environment.
The above answer is partially true. An allele's frequency may also change due to genetic drift.
Evolution. Interesting way to put, evolution is the change in allele frequency over time in a population of organisms.
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
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.
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
Evolution; the change in allele frequencies over time in a population of organisms.
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.

Evolution. Interesting way to put, evolution is the change in allele frequency over time in a population of organisms.
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.
Generation-to-generation change in allele frequencies in a population is known as evolution. This change can be the result of various factors such as natural selection, genetic drift, gene flow, and mutation. Over time, these processes can lead to the emergence of new traits and variations within the population.
FOR PENNFOSTER....the answer is C) genetic drift
genetic drift
Allele frequencies remain constant in a population when certain conditions are met, such as no mutations, no gene flow, random mating, a large population size, and no natural selection. Genotype frequencies can change over time due to factors like genetic drift, natural selection, and non-random mating. As long as the conditions for constant allele frequencies are maintained, the overall genetic makeup of the population remains stable even as individual genotypes may change.
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.
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
