What are two basic ways that organisms reproduce?
Mitosis and Meiosis.Mitosis - Cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus; occurs in somatic (body) cells.Meiosis - Cell division that results in four daughter cells each with half the number of chromosomes of the parent cell; occurs in productions of gametes (sex cells).
The cell division process that only occurs in specific cells and at specific times is?
The cell division process that only occurs in specific cells and at specific times is called mitosis. Mitosis is a type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. It is essential for growth, repair, and maintenance of multicellular organisms.
What happens during g2 phases?
Chromosomes are checked for errors.In the G2 phase, growth and preparation for cell division occurs.
What mutation cause changes in the number of chromosome?
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
What cell division forms sperm and ova?
Meiotic Cell Division- occurs only in the production of ova and sperm. It producesfour daughter cells that contain only half the number of chromosomes as found in the parent cell.;) Awesome

The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
When does the second mitotic division occur in the egg?
The second mitotic division in the egg typically occurs after fertilization by the sperm. This division takes place once the zygote has formed and involves further division of the replicated chromosomes to generate daughter cells with the full complement of chromosomes.
Where does nondisjunction occur in the process of cell division?
Nondisjunction occurs during the separation of chromosomes in either meiosis or mitosis, leading to an abnormal number of chromosomes in the resulting cells.
What mutation cause changes in the number of chromosome?
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
What is the definition of meoisis in anatomy?
Meiosis is a type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division that result in the production of four daughter cells, each with half the number of chromosomes as the original parent cell. Meiosis is necessary for the formation of gametes (sperm and egg cells) and contributes to genetic variation.

The reduction division that separates two hapliod complements from each other is called what?
The reduction division that separates two haploid complements from each other is called meiosis. Meiosis is a type of cell division that occurs in sexually-reproducing organisms, resulting in the formation of gametes (eggs and sperm) with half the number of chromosomes as the parent cell.
What important event occurs to chromosomes during interphase?
An important event that occurs during interphase is chromosome duplication (the uncoiling of the DNA). This prepares the cell for cell division as the cells are still growing during interphase.
In what types of organisms does meiosis occur?
Meiosis occurs in sexually reproducing organisms, including most eukaryotes such as plants, animals, and fungi. It is a process that produces gametes, which are specialized sex cells with half the number of chromosomes as the parent cell.
