At the beginning of mitosis, a mosquito cell has six double-stranded chromosomes. This cell will have split into two daughter cells with six chromosomes each at the end of mitosis. Consequently, 6 chromosomes will be provided to each daughter cell (single-stranded).
<h3>
What is mitosis?</h3>
One cell divides into two genetically identical daughter cells during the cell duplication process known as mitosis. The cell's chromosomes are duplicated throughout the process of mitosis and then divided equally between the two daughter cells' two new nuclei.
Every chromosome acquires identical copies of the parent cell's DNA thanks to anaphase. At their centromere, the sister chromatids divide in half to form distinct, identical chromosomes.

Answer:
A mutation is:
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
What causes a mutation:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
Short Version: environmental factors, cell division, Change in DNA
What is the evolutionary importance of mutations:
A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation.
Short Version: Without mutations then we wouldn't have evolution meaning if one new predator were to be introduced it can completely whipe out that entire species.
