Question
Chapter 16, Problem 29P
Summary Introduction
To analyze:
The description of the two processes by which duplicate genes arise.
To determine the possible fates of duplicate genes.
Whether type of duplication have an impact on possible fates.
Introduction:
The process responsible for the generation of a new gene with time is gene duplication. Gene duplication facilitates the evolution of a complex organism. Gene duplication allows specialization which sequentially permits a large physiological change during the course of evolution.
