A DNA mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. DNA mutations can affect an offspring can result in abnormal protein products. Mutations can also introduce new alleles into a population of organisms and increase the population's genetic variation.
The correct answer is C. It is a sudden change that causes species to become extinct.
This answer is not correct because evolution occurs over a long period of time, as evidenced by the theories that describe its timeline (including gradualism and punctuated equilibrium). Additionally, evolution does not always involve the extinction of a species, but it can.

During mitosis, the chromosome copies separate the nucleus divides and the cell divides. This produces identical two cells called daughter cells. The main purpose of mitosis is for growth and to replace worn out cells.
Answer:
The frequency of animals in population one to carry both alleles in 1&3 is .85%.
