Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes.
Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes.
Meiosis has 2 cellular divisions, while mitosis only has one.
They are both necessary to support life, and they both produce Diploid cells in the first division.
Also, from a similar topic in Yahoo Answers (Which has a much better explanation) :
Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division)
Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction.
Meiosis consists of two divisions:
Meiosis I halves the number of chromosomes to give 2 X haploid cells.
Meiosis II doubles the number of cells to give 4 X haploid gametes.
Two processes during meiosis I increase variation .
In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material.
In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random.
Both of these increase variation to produce four genetically different gametes at the end of meiosis II
DNA replication only occurs once, before Meoisis I.

What Variations of homologous genes that result in differences in structure and function are?
These variations are called paralogs. Paralogs are genes that arise from gene duplication events and can evolve to perform different functions. Despite their structural similarities, paralogs can have distinct roles in biological processes.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids that are held together by a centromere. These sister chromatids contain the genetic information needed for the cell to function and are divided evenly between the two daughter cells during cell division.
What are the key differences between euchromatin and heterochromatin in terms of their structure and function?
Euchromatin is less condensed and actively transcribed, while heterochromatin is highly condensed and transcriptionally inactive. Euchromatin is involved in gene expression, while heterochromatin plays a role in gene silencing and maintaining chromosome structure.
What is the terms refers to a region of a chromosome that has a specifiic function?
The region of chromosome that is generally thought of as the unit of function is the "gene". Genes are composed of both a "coding region"--that sequence that tells the cell's machinery what the protein will be--and a "regulatory" region, which tells the cell when to turn on the coding region to make the protein.
What is the function of centromere?
The centromere is a region of a chromosome that helps in the process of cell division. It plays a crucial role in ensuring that each daughter cell receives the correct amount of genetic material. The centromere also serves as the attachment point for spindle fibers during mitosis and meiosis.

What similarities and differences do you see between the function and linear equations?
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.
What is the procedure called of comparing cultural similarities as well as differences among societies?
The procedure is called cross-cultural analysis, which involves examining and analyzing the similarities and differences in cultures across societies. This method helps in understanding how different societies function and how culture shapes human behavior in various contexts.
What are chromosomes function?
a chromosome carries millions of genes
Nature of daughter cells in mitosis?
The daughter cells produced in mitosis are genetically identical to the parent cell and to each other. They have the same number of chromosomes and contain an identical set of genetic information. This ensures that each daughter cell can function properly and carry out the same functions as the parent cell.
What are the Similarities in turkey vultures and black vultures?
Both vultures and ptarmigan are birds, vertebrates and consumers. But that's where the similarities end. Differences include plumage coloring in bearded vultures and red knots may serve a cosmetic function whereas in rock ptarmigan the function appears to be camouflage. Other differences can be found in the related question below.
What are similar but not identical are what?
Similar but not identical things share common characteristics but also have differences that set them apart. They may have similarities in aspects such as appearance, behavior, or function, but there are variations that make them distinct from each other. These differences help to differentiate and classify them within their respective categories.
What are the similarities between quadratic function and linear function?
Both are polynomials. They are continuous and are differentiable.
What relates the structure of the Cell to the Cells function?
It's chromosome complement.
Which finite differences are constant for a quartic function?
For a quartic function, the second and fourth finite differences are constant. The first finite differences will vary, while the second differences, representing the change in the first differences, will become constant. The fourth differences will also be constant because the quartic function is a polynomial of degree four.
What is the chromosome is?
Chromosomes are structures composed of DNA and proteins. They carry the genetic information of the cell. In eukaryotic cells they are located in the nucleus.
What is the function of each chromosome?
Chromosomes contain genetic information in the form of DNA, which carries instructions for cell function, growth, and development. Each chromosome carries specific genes that determine traits and characteristics of an organism. During cell division, chromosomes ensure that genetic information is accurately replicated and passed on to new cells.
