i have no clue what the answer is just get a dictionary
What else can I help you with?
If the original cell that divides by meiosis diploid or haploid?
The original cell that undergoes meiosis is diploid, meaning it contains two sets of chromosomes. This diploid cell, typically a germ cell, divides through meiosis to produce haploid gametes, which have only one set of chromosomes. This reduction in chromosome number is crucial for sexual reproduction, ensuring that when gametes fuse during fertilization, the resulting zygote restores the diploid state.
How many diploid cells does mitosis end with?
Mitosis ends with two diploid cells. During this process, a single diploid parent cell divides to produce two genetically identical daughter cells, each with the same number of chromosomes as the original cell. This ensures that the diploid chromosome number is maintained in the resulting 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.
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.
What happens to the polar body during the process of oogenesis?
During oogenesis, the polar body is a small cell that is formed as a byproduct when the egg cell divides. The polar body typically does not have the ability to develop into a mature egg cell and eventually disintegrates.
If the original cell that divides by meiosis diploid or haploid?
The original cell that undergoes meiosis is diploid, meaning it contains two sets of chromosomes. This diploid cell, typically a germ cell, divides through meiosis to produce haploid gametes, which have only one set of chromosomes. This reduction in chromosome number is crucial for sexual reproduction, ensuring that when gametes fuse during fertilization, the resulting zygote restores the diploid state.
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.
How many diploid cells does mitosis end with?
Mitosis ends with two diploid cells. During this process, a single diploid parent cell divides to produce two genetically identical daughter cells, each with the same number of chromosomes as the original cell. This ensures that the diploid chromosome number is maintained in the resulting cells.
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.
