1. Which describes the outcome of both vertical and lateral gene transfer?

leads to rapid evolution of a population

increases variability in a population

results in large changes to the genetic code

occurs between nonrelated organisms

are types of mutation

2. Which of the following occurs in vertical gene transfer, but does not occur in horizontal gene transfer?

a type of asexual reproduction

rapid evolutionary changes

the use of a sex pilus

interaction between parent and offspring

plasmid transfers

3. Which of the following best describes the role of vertical gene transfer in evolution?

The types of genes passed on in vertical gene transfer are determined by artificial selection.

Vertical gene transfer is not affected by fitness.

Vertical gene transfer involves sexual reproduction that increases variation.

Mechanisms of evolution do not act on processes of vertical gene transfer.

Organisms that utilize vertical gene transfer have an increased chance of mutation.

4. Which of the following is not part of the process of bacterial conjugation?

plasmids

F+ cells

F– cells

sex pilus

bacteriophage

5. Based on the role of gene transfer in populations, which process will not increase variability in a population?

sexual reproduction

conversion

conjugation

transformation

transduction
