Yes, allele frequencies are more likely to remain stable in large populations due to the effects of genetic drift being more pronounced in small populations. In small populations, random events can lead to significant changes in allele frequencies, whereas in large populations, genetic drift has less impact and allele frequencies are more likely to remain stable over time.
False. Genetic drift is more likely to occur in small populations where chance events can have a greater impact on allele frequencies. In large populations, genetic drift is typically less influential compared to other evolutionary forces.
Extinction
Small populations
Genetic drift is more pronounced in small populations because chance events can have a greater impact on allele frequencies. In contrast, in large populations, genetic drift is less influential due to the dilution effect of a larger gene pool.
small populations where random events can have a significant impact on allele frequencies over time.
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.
No
Genetic drift is most likely to occur in small populations where random events can have a greater impact on allele frequencies. It is also more common in isolated populations with limited gene flow from other populations.
a larger population would feed on the fewer population because the population is small and it is less likely for them to defend themselves. and pretty soon when both populations aren't balanced out the bigger population overtakes the fewer population and leads to extinction
Mutation rates are small but constant. With a typical mutation rate of 1 x 10-6, it is expected that 1 out of a million individuals in a population will carry the mutation. If the population size is small (10,000 or fewer individuals), the probability that the mutation will be present is small (~1% with 104 individuals). If population sizes are large (107 or more individuals), the probability that the mutation will be present is large (~10 mutants expected if 107 individuals are in the population). Mutations can be lost from populations through genetic drift, and large populations experience less genetic drift than small populations. Thus mutations are more likely to exist and persist in large populations than in small populations.
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
