which of the following best explains how genetic recombination influences evolution?

Causes. Four classes of mutations are (1) spontaneous mutations (molecular decay), (2) mutations due to error-prone replication bypass of naturally occurring DNA damage (also called error-prone translesion synthesis), (3) errors introduced during DNA repair, and (4) induced mutations caused by mutagens.

What genetic mutations are caused by external factors?

Acquired (or somatic) mutations occur at some time during a person’s life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if a mistake is made as DNA copies itself during cell division.

What describes how genetic drift occurs quizlet?

Genetic drift that occurs when a few individuals become isolated from a larger population, with the result that the new population’s gene pool is not reflective of the original population. Graded variation in some traits of individuals that parallels a gradient in the environment.

Which of the following describes what occurs in genetic drift?

Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.

Which one of the following is the best definition of evolution?

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.

Which of the following processes create genetic diversity?

Two processes that can create genetic diversity in a population are mutation and recombination.

Which of the following processes contributes to creating genetic variability in the offspring?

Meiosis involves two divisions and produces four nonidentical gametes. Which of the following processes contributes to creating genetic variability in the offspring? … meiosis produces haploid gametes, and fertilization creates a diploid cell that divides by mitosis to produce a new individual.

Which cellular process creates genetic diversity?

Genetic diversity is the result of two processes known as mutation and recombination. Genetic diversity can be seen in individuals within a population.

How does genetic variation and environmental factors contribute to evolution?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. … Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

What factors influence the rate of evolutionary change in a species quizlet?

The factors are rate of environmental change, genetic variation, population size, and generation time.
