Which mechanisms of evolution can produce populations that are LESS fit over time? (Select all that apply)
A. Genetic Drift
B. Natural Selection
C. Artificial Selection
D. Sexual Selection
Homework Answers
When a population is not under Hardy Weinberg equilibrium, several mechanisms can take place to cause evolution in the population which in simple terms is change in allelic frequency of the population.
The four options given in this questions can change the allelic frequency or we can say, this may result in evolution.
But all mechanisms of evolution will not result in fittest population in the future.
Among given options, when there is sexual selection, this may result in less fit population in future.
For example, by sexual selection, more colorful and attractive individuals will be born, which will get easily hunted by the predators.
In genetic drift also, there is chance variation of individuals to pass on their genes to next generations as there is random sampling. Hence, when an individual will not be able to reproduce, then the healthy gene may get slowly diluted or removed from the population, thus producing unfit offsprings.

Questino 7. How I genetic drift different from natural selection? A. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B. Natural selection has a stronger effect in large population, whereas genetic drift acts primarily in small populations. C. Natural selection is a mechanism of evoltion, whereas genetic drift is not a mechnaism but an outcome of evolution. D. Natrual selection tends to cause very rapid evolution whereas gentic drift tends to...
We base our interpretation of evolutionary change in allele frequencies on predictions made using the Hardy-Weinberg Equilibrium (HWE) equation
2. We base our interpretation of evolutionary change in allele frequencies on predictions made using the Hardy-Weinberg Equilibrium (HWE) equation as a baseline hypothesis of "No change". Which one, of the following mechanisms of evolution tends to produce such small changes over time in large populations that is practically undetectable except of very long time periods in anyu case. a) Selection b) Migration c) Genetic Drift d) Inbreeding

6. Which of these conditions will lead to evolution by natural selection? a. Heavy metal pollution reduces reproductive success of all phenotypes of green algae in the pond. b. Variation among individuals is not genetic; instead it results from learned behavior or physiological environmental responses. c. Introduction of an exotic predator species results in one native prey phenotype evading predation while other phenotypes get eaten. d. Individuals of the population are clones (genetically identical). 7. Which one is used as...

Genetic drift can be an important evolutionary process. This is due to the fact that (A natural selection acting on the genetic variation of a large population B small isolated populations are unable to defend themselves from predators, therefore they loos genetic diversity. Natural selection, in this case, has less variation to work with. C when genetic drift is the only evolutionary process at work, one allele may be lost forever and the other may become fixed (100% frequency). D)...

1:2025 SPRE 14. As long as there are multiple alleles of a gene in a population, why will the frequencies of the alleles always change over time? a. Because natural selection changes all allele frequencies in populations over time. b. Because genetic drift causes random fluctuations of allele frequencies in populations. c. Because diseases will eliminate some of the alleles, generating fluctuations in their frequencies. d. Because allele frequencies fluctuate before...
