B. four different 1n cells
In oogenesis, a diploid reproductive cell (oogonium) divides meiotically to produce one haploid egg cell (ovum) and one or more polar bodies. The egg cell is then fertilized by a sperm cell to form a zygote.
It depends on what you're talking about mitosis or meiosis.
Mitosis- 2n~2n, for somatic cells (body cells) which aid in growth & repair.
Meiosis- 2n~n, for the testes & ovaries (Germ cells), that makes sperm and egg cells

What is asexual reproductive process in which the cell divides into two separate genetically identical cells?
Binary fission is the asexual reproductive process in which a single cell divides into two separate genetically identical cells. This process is common in prokaryotes such as bacteria and archaea.
What is the diploid number of an amoeba?
The diploid number of an amoeba is generally two. This means that it has two sets of chromosomes in its nucleus. Amoebas reproduce through binary fission, a form of asexual reproduction where the parent cell divides into two identical daughter cells.
What happens when egg and sperm are formed in meiosis?
In meiosis, egg and sperm are formed from a specialized cell division process where a single diploid cell divides twice to produce four haploid cells. During this process, genetic material is shuffled and recombined through crossing over, resulting in genetic diversity among the resulting eggs and sperm. This genetic diversity is essential for sexual reproduction and the creation of genetically unique offspring.
Are gametes haploid offspring haploid or diploid?
Gametes are haploid cells, meaning they have half the number of chromosomes as diploid cells. Offspring resulting from the fusion of gametes are usually diploid, with the full set of chromosomes from each parent.
Which statement is true about meiosis Meiosis is a process that duplicates and divides the nuclear contents only?
This statement is false. Meiosis is a process in which a diploid cell divides to produce four haploid cells. It involves two rounds of cell division, resulting in genetic variation through crossing over and independent assortment.
In oogenesis a diploid reproductive cell divides meiotically to produce?
one haploid gamate
During what cell division process are egg cells made?
Duringoogenesis, the production of egg cells take place. In oogenesis, a diploid reproductive cell divides meiotically to produce one mature egg cell (also called ovum). During cytokinesis and cytokinesis two of oogenesis, the cytoplasm of the original cell is divided unequally between new cells. As a result only one mature egg cell is produced by meiosis, the other three eggs are called polar bodies and will eventually degenerate
Summarize the major characteristics of spermatogenesis and oogenesis?
Spermatogenesis is the process by which diploid cells in the testes undergo division and differentiation to form haploid sperm cells. It involves mitosis, meiosis, and cellular differentiation to produce four functional sperm cells. On the other hand, oogenesis is the process by which diploid cells in the ovaries develop into mature egg cells. Unlike spermatogenesis, oogenesis only produces one mature egg cell per cycle and involves unequal division of cytoplasm between the resulting cells.
How many times does a reproductive cell divide during meiosis?
A reproductive cell divides twice during meiosis, resulting in the formation of four haploid daughter cells. Each division includes separate stages called prophase, metaphase, anaphase, and telophase.
During meiosis each diploid parent cell divides and produces haploid daughter cells?
Yes.
How is speciation and reproductive isolation related?
Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
In which phase are the spindle broken down the chromosome uncoil and the cytoplasm divides to yield two new diploid cells?
telophase telophase
What is asexual reproductive process in which the cell divides into two separate genetically identical cells?
Binary fission is the asexual reproductive process in which a single cell divides into two separate genetically identical cells. This process is common in prokaryotes such as bacteria and archaea.
Is a chicken egg diploid or haploid?
A chicken egg is diploid because it contains the genetic material from both the mother (hen) and father (rooster) chickens that fertilized the egg. Diploid means it has two sets of chromosomes, one set from each parent.
Where the nucleus of a diploid cell divides in order to form new haploid cells is called?
Nucleus divided to form haploid cells.Process is called meiosis.
What is mitosis about?
Mitosis is the process a single cell divides into two diploid cells. Each cell has the same amount and quality of chromosomes as the parent cell.
Does mitosis start with one diploid cell?
Yes, mitosis typically begins with a single diploid cell that contains two copies of each chromosome. During mitosis, this cell divides into two daughter cells that are genetically identical to the parent cell.
