Question
Chapter 19, Problem 10TY
Summary Introduction
Introduction: Horizontal gene transfer can be defined as the exchange of genetic contents between the unicellular and multi-cellular organisms that do not include the transmission of DNA from parent to offspring. This process is responsible for evolution by mixing the genetic material of two species.

Horizontal gene transfer is a process in which genetic material from an organism is
a. transferred from cell to cell.
b. transferred to its offspring.
c. transferred to another organism that is not the offspring of the first organism.
d. released into the environment.
Are gene mutations caused by selective pressures in the environment? In other words, do gene mutations arise in an organism out of need or want?
Group of answer choices
A. No, because gene mutations are not purely random.
B. Yes, because gene mutations are not purely random.
C. No, because gene mutations are purely random.
D. Yes, because gene mutations are purely random.
