Chapter 26.5, Problem 2CC
Summary Introduction
To explain: The reason why numerous base changes in a genome have no effect on the organism’s fitness.
Concept introduction:
Mutations are heritable changes in the genome. It causes diversity in genes. Mutation may be due to chromosomal rearrangement or base changes in DNA such as

MOLECULAR BIOLOGY (DNA/PROTEIN SEQUENCES) Scientists use DNA/protein sequences to figure out which organisms are most closely related to each other. Cytochrome c is a protein found in mitochondria used in the study of evolutionary relationships among organisms.
