Why mitotic cell division is called homotypic cell division?
Mitotic cell division is called homotypic cell division because no crossing over is occur in this division and pairing of homologous cromosome is also not occur. So caracteristics of daughter cells is same as mother cell. As there is no variation occur, so this type of cell division may called homotypic cell division.
What is Non viable zygotes?
Non-viable zygotes are fertilized eggs that do not develop successfully into viable embryos. This can occur due to various genetic abnormalities, issues during fertilization, or problems with cell division. As a result, these zygotes fail to implant in the uterus or lead to a pregnancy. In many cases, non-viable zygotes are naturally expelled by the body without the woman being aware of the pregnancy.
When does fertilization in mitosis occur?
Fertilization in mitosis occurs when the sperm and egg cells fuse during sexual reproduction, typically in the reproductive organs of plants and animals. This fusion of gametes results in the formation of a zygote, which then undergoes mitotic cell division to develop into a new organism.
What type of cell division can occur in both haploid and diploid cells?
Meiosis is a type of cell division that can occur in both haploid and diploid cells. In haploid cells, meiosis produces gametes (sex cells) with half of the genetic material, while in diploid cells, it helps in producing haploid cells for sexual reproduction.
When DNA divides what event must occur if a nucleus containing this molecule undergos mitotic cell division?
Before a nucleus can undergo mitotic cell division, the DNA must replicate during the S phase of the cell cycle to ensure that each daughter cell receives a complete and identical set of genetic information. This ensures that each new cell will have a full set of genetic instructions necessary for proper cell function and growth.
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.
Why mitotic cell division is called homotypic cell division?
Mitotic cell division is called homotypic cell division because no crossing over is occur in this division and pairing of homologous cromosome is also not occur. So caracteristics of daughter cells is same as mother cell. As there is no variation occur, so this type of cell division may called homotypic cell division.
Where else in a plant might you find a large amount of mitotic cell divisions occurring?
Mitotic cell division refers to the division of the mother cell into two daughter cells. In plants, a large amount of mitotic cell divisions occur in the terminal buds, shoot tips and in the vascular cambium.
What are the two disjunctionsthat can occur?
Mitotic or meiotic, depending on whether ordinary cell division or gamete production is involved.
What is Non viable zygotes?
Non-viable zygotes are fertilized eggs that do not develop successfully into viable embryos. This can occur due to various genetic abnormalities, issues during fertilization, or problems with cell division. As a result, these zygotes fail to implant in the uterus or lead to a pregnancy.

During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
What day does first cell division occur in pregnancy?

What process must occur first before any cell division can takes place?
Before any cell�division to occur, everything must be duplicated. That occurs during inter-phase before mitosis or meiosis begins or occurs. Fertilization -apex-
When does cytokinesis occur in cell cycle?
It usually occurs in telophase of mitosis and in the M (mitotic) phase.
