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.

Which of the following statements describes an example of genetic drift?a. Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.

Hardy Weinberg equilibrium (HWE) describes a situation in which the relative frequencies of alleles do not change over generations. which of the following could prevent HWE from being maintained? A. New mutations B. All individuals reproducing equally C. Random mating D. No individuals entering the population

A population of gophers is very isolated, so no individuals can move in/out of the population. It is very small, so random events affect allele frequencies and many traits are under strong selection. Males are chosen randomly. Which statement is correct? A. Allele frequencies in 10 generations will be different than they are today. B. Individual gophers are evolving traits they need to survive C.Genetic drift is not acting on the gophers D. The population is in Hardy-Weinberg equilibrium
