What are daughter nuclei formed from during cell division?

Daughter nuclei are formed as a result of the mitosis process, which is a type of cell division that occurs in somatic (body) cells. During mitosis, a single parent cell divides to produce two genetically identical daughter nuclei. This process involves several stages, including prophase, metaphase, anaphase, and telophase, where the chromosomes are duplicated and evenly distributed to ensure that each daughter nucleus receives a complete set of genetic material.

While meiosis also results in daughter nuclei, it specifically leads to the formation of gametes (sperm and eggs) and is characterized by a reduction in chromosome number. The options regarding the replication of organelles and Mendelian inheritance do not relate directly to the formation of daughter nuclei during cell division. Organelles replicate as part of the cell's preparation for division but are not the source of daughter nuclei, and Mendelian inheritance describes the inheritance patterns of traits rather than the actual process of cell division. Thus, the correct answer reflects the direct mechanism by which daughter nuclei are generated during cell division.
