The parent cell is called a cell to the daughter cells.

Explanation:

This introduces the concept of mitosis and meiosis in the form of a Leukemia case study. Cell division is the process in which one cell, called the parent cell, divides to form two new cells, referred to as daughter cells. Mitosis actually occurs in four phases: prophase, metaphase, anaphase, and telophase.

The parent cell is called a diploid cell to the daughter cells.

Explanation:

Meiosis starts with a diploid parent cell, meaning it has two copies of each chromosome. The parent cell undergoes one DNA replication round followed by two different nuclear division rounds. The method results in four haploid daughter cells, ensuring they carry half the diploid parent cell chromosomes.
