The evolution is the process by which the heritable characteristics of an organism changes over successive generations. It is often resulting in new species development. These heritable characteristics are the expressions of genes that passed during reproduction from parent to offspring.

Summary Introduction

Introduction: The evolution is the process by which the heritable characteristics of an organism changes over successive generations. It is often resulting in new species development. These heritable characteristics are the expressions of genes that passed during reproduction from parent to offspring.

Expert Solution & Answer

Explanation of Solution

Correct answer: Option c. change allele frequency in a population.

Reasons for the correct answer:

There are four forces of evolution include mutation, genetic drift, natural selection, and gene flow can all change the allele frequencies in a population.

Option c. is given as “change allele frequency in a population”.

Hence, option c. is correct.

Reasons for the incorrect answers:

Option a. is given as “create new alleles that have never existed before”. Mutation, duplication, or other processes can produce new alleles and genes and increase genetic variation, but natural selection, genetic drift, gene flow does not create new alleles. Hence, option a. is incorrect.

Option b. is given as “increase reproduction success of individuals in a population”. The reproduction success of individuals in a population does not increase by the four forces of evolution. Hence, option b. is incorrect.

Option d. is given as “drive alleles to become lost or fixed in a small population”. Genetic drift is the process through which allele frequencies within a population fluctuate but natural selection, gene flow, and mutation do not fix allele in a population. Hence, option d. is incorrect.

Therefore, options a., b., and d. are incorrect.

Conclusion

The natural selection, mutation, gene flow, genetic drift are the four forces of evolution that can change allele frequency in a population.

Students have asked these similar questions

Biologists sometimes say that “natural selection depends on the specific environment where a species lives.” What does this statement mean? A) A) If populations of a species are in different environments, traits that individuals need to meet their needs in each environment will appear. B) Traits can be helpful or harmful. If populations of a species are in different environments, some traits that are helpful in one environment might be harmful in another environment. C) Traits are always either helpful or harmful, and the environment of a population doesn’t matter. If populations of a species are in different environments, the same traits will always be helpful. D) Species were formed to perfectly match their environment. The traits of individuals in a species depend on the specific environment in which they were created.

With stronger natural selection, was the more beneficial allele lost from these small populations?a) It was lost very frequently, and the strength of natural selection did not make any difference.b) It was never lost.c) It was lost a few times, but not very often, and it was lost less frequently under strong selection.d) It was lost a few times, and it was lost more frequently under strong selection.

Darwin based his Theory of Evolution by Natural Selection on series of observations. Which of the following is not associated with his theory? a) individuals in a population vary phenotypically b) organisms tend to under-reproduce themselves c) there are limited resources for which individuals compete d) some variations possessed by individuals of a population are inherited
