Final answer:
Mitosis results in two daughter cells that are genetically identical to the parent cell, ensuring the maintenance of genetic information across cell divisions.
Step-by-step explanation:
The end result of mitosis is option D: Offspring that are genetically identical to their parents. Mitosis is a process of asexual reproduction that results in two daughter cells that have the same number of chromosomes and are genetic clones of the parent cell. It is important for growth, tissue repair, and asexual reproduction in single-celled organisms. Unlike meiosis, which leads to genetic variation through the production of gametes, mitosis ensures that the new cells maintain the same genetic information as the original cell.
