Meiosis does not end with the production of diploid cells; instead, it results in the formation of haploid gametes (sperm and eggs in animals). Additionally, meiosis does not involve the duplication of chromosomes in the second division, which is a key difference from mitosis. Instead, it consists of two rounds of division—meiosis I and meiosis II—without an intervening round of DNA replication.

How do meiosis 1 differ from those of meiosis 2?
Anaphase of Meiosis 1 separates the homologous chromosome pairs, but during Anaphase of Meiosis 2, the sister chromatids are separated instead. Also, Meiosis 1 starts with one diploid cell and ends with 2 haploid cells, whereas Meiosis 2 starts with the 2 haploid cells and ends with 4 haploid cells (gametes).
Daughter cells become haploid during what stage of meiosis?
During a process called 'meiosis' at the end of telophase which ends in cytokinesis - the process by which the daughter cells separate.
What is the events of meiosis?
Meiosis' two main effects are the fact that it keeps the number of chromosones from doubling each generation, and it provides genetic diversity in offspring. The Phases of Meiosis go like this: Interphase, prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, and telophase 2. When this process ends the result is four daughter cells. Hope this helped
Why do the 4 resulting cells of meiosis do not have paired chromosomes?
The four resulting cells of meiosis do not have paired chromosomes because meiosis involves two rounds of cell division—meiosis I and meiosis II. During meiosis I, homologous chromosomes are separated into different cells, reducing the chromosome number by half, while meiosis II separates sister chromatids. As a result, each of the four daughter cells ends up with a haploid set of unpaired chromosomes, each containing one chromosome from each homologous pair. This process is essential for sexual reproduction, ensuring genetic diversity and the proper chromosome number in offspring.
Which phase of mitosis does the centromere divide chromatids split and identical chromosome move to opposite ends of the cell?
metaphase I of meiosis
How many cells does meiosis end in?
Starts in 1 and ends in 4
What is the phase of mitosis or meiosis when choromose sperate to opposite ends of the cell?
In mitosis it is anaphase. In meiosis it is anaphase I and anaphase II.

How much DNA would a gamete contain if the DNA was also replicated between meiosis you and meiosis ii?
A gamete would contain the haploid amount of DNA, which is one complete set of genetic material. During meiosis, DNA is replicated once during S phase but is not copied again between meiosis I and meiosis II, so each gamete ends up with a single set of chromosomes.
Is the parent cell diploid a characteristic of meiosis not mitosis?
Mitosis starts with a diploid parent cell and ends with two diploid daughter cells. Meiosis starts with a diploid parent cell and ends with haploid daugther cells. The number of cells produced depends on the type of gamete being generated.
When does independent assortment occur in meiosis?
Independent assortment occurs in meiosis during metaphase I when homologous chromosomes align randomly at the metaphase plate. This allows for different combinations of alleles to be present in the gametes produced.
Which phase of meiosis do sister chromatids pull apart and move to opposite ends of the cell?
Sister chromatids are pulled apart from each other during the anaphase II stage of meiosis II. From there the chromatids are taken to opposite poles of the cell and create two haploid cells.
What are the two distinct stages of meiosis?
Meiosis I and meiosis II

What are three differences between mitosis and meiosis?
Here are two; mitosis ends in cell division while meiosis ends with gamete division, and mitosis ends with a chromosome number of 2N while meiosis ends with a chromosome number of 1N - give us the third.
