Answer :
A mutation that knocked out the proofreading function of DNA polymerase would result in a higher-than-normal rate of DNA synthesis errors.
What do you mean by mutation?
The entire human species shares the same genes. Alleles, which are small variations of the same gene, are produced via mutation. Every person is different due to these minute variations in DNA sequence. They explain the variety in human height, form, behavior, skin color, hair color, and susceptibility to disease that we observe. Other species' individuals differ from one another in terms of both appearance and behavior.
Genetic diversity is advantageous because it aids in the evolution of populations. The next generation inherits variations that assist an organism live and procreate. Variations that make it difficult for individuals to survive and procreate are removed. Natural selection has the power to drastically alter an individual's physiology, behavior, or outward appearance in a group.
