Question
Chapter 5, Problem 5.6CR
Summary Introduction
To determine: The similarity in the gene sequence between humans and fruit flies, fish, and mice.
Introduction: The organisms are classified into different groups on the basis of their similarities. The animal kingdom is classified into vertebrates and invertebrates. The vertebrates are further divided as fish, amphibians, reptiles, birds, and mammals based on their features. The more closely related groups have a higher similarity in their gene sequences.
