In a one word response, mitosis.
In an explanation: Before the replication process, an ordinary sex cell contains only has 23 chromosomes. That is half the amount of a normal cell. So when the cells join together they make up the 46 pairs. Then through replication and division(i.e mitosis), the cells are copied to form in short a tiny human. You then forever live with the same amount of chromosomes in your normal cells.
Explanation:
1. Barr body is a drumstick-like structure of dense, coiled chromatin that appears normally in female's buccal cells and neutrophils. It represents the inactive X-chromosome (Females have two X-chromosomes. Only one is active.)
2. Liver cells are somatic, not sex cells and are thus diploid.
Answer: "lacto-ovo-vegetarian" .

Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
