Why should the gametes be haploid when the new organism will be diploid?

Gametes are another name for sex or sperm cells. When two haploids come together they form a zygote and therefore a diploid.

If the diploid number of chromosomes for an organism is twenty-six what is the haploid numbe?
The haploid number is half of the diploid. Therefore the haploid number in this case is 12.
Do sperm cells have diploid number?
Gametes are haploid and each contain only one chromosome. When a male and female haploid gamete unite , they create a diploid zygote.
Why do the chromosomes on hapliod cells that are produced by meiosis 1 look different from those produced by meiosis 2?
Meiosis I should not produce haploid cells. They should be diploid because before meiosis I the diploid cell duplicated its DNA. It is only after Meiosis II that the four cells are haploid.
Does a cell in metaphase 2 have the same mass of DNA as a diploid cell in the g1 phase both cells are coming from the same animal?
the diploid means (2n) set up of the haploid number,haploid number present either in gametes either sperm or in ova, after fertilization a zygote become (2n) ,as there is various kind of phylum (Drosophila =2n=8,but human's 2n=46,chromosomes) chromosomes retain dna and protein,so we can say , the fluctuation in chromosome number should be along with dna quantity. further inquiry:9563174075
Does the cell divide in two during mitosis?
No, because gametes do not divide. Specific cells called "germ cells" give rise to gametes through a process called meiosis. After that gametes do not divide again and simply wait until an opportunity arises in which they can pair up with their other gamete cell and form a zygote.

Does meiosis occur in diploid cells?
First off, your query should be "Do mitosis and meiosis produce diploid cells?" The answer is that mitosis produces diploid cells, since mitosis is used to replace body cells, but meiosis produces haploid cells, since meiosis is used to produce sex cells. The sex cells are haploid because a sex cell eventually combines with another sex cell to create a new organism.

Why must gametes undergo meiosis instead of mitosis?
Gametes don't undergo Meiosis, but are CREATED in Meiosis.Gametes should be haploid. Otherwise chromosomal number will be doubled in offspring
What happens to a 2n cell during meiosis?
2n in cytoplasm refers to the diploid number of chromosomes in a cell. Diploid means that two sets of chromosomes are present in the cytoplasm. In humans the diploid number is 46 chromosomes. This means that in human cells the 2n in cytoplasm is 46. In other organisms the 2n in cytoplasm can vary. For example: In fruit flies the 2n in cytoplasm is 8. In nematodes the 2n in cytoplasm is 6. In wheat the 2n in cytoplasm is 42.The 2n in cytoplasm can be used to distinguish between haploid and diploid organisms. Haploid organisms such as yeast have only a single set of chromosomes in the cytoplasm. Diploid organisms such as humans have two sets of chromosomes in the cytoplasm.

What is the first haploid stage of spermatogenesis?
In humans, cells are usually diploid or haploid. Diploid cells are two complete sets of chromosomes. At fertilization, we usually receive one complete set of chromosomes from each parent. Most of our body is diploid. Haploid cells have one complete set of chromosomes. Sex cells (sperm and eggs) are usually haploid. When two haploid cells fertilize each other, the resulting diploid cell can grow into a normal diploid embryo and ultimately to a full grown adult. Mitosis produces diploid cells and is called mitotic cell division. Meiosis produces haploid cells and is called meiotic cell division. The stages that describe the process of cell division are the same in both mitosis and meiosis. They are Prophase, Metaphase, Anaphase and Telophase. Mitosis and meiosis are part of a larger process called the cell cycle. The stage interphase is part of the cell cycle, but not part of either mitosis or meiosis. Meiosis consists of two rounds of cell division. The stages are distinguished from each other by using the Roman numerals I and II after the stage name, as in Metaphase I and Metaphase II. One full round of meiosis is Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and finally Telophase II. Meiosis I the cell division that moves the cells from diploid to haploid. The exact stage of Meiosis I that moves the cell from diploid to haploid can be debated. Prophase I and Metaphase I are not options because the chromosomes have not really started to separate yet. Anaphase I is the first realistic answer because the chromosomes begin to separate. Telophase I shows the chromosome completely separated but the cell has not yet become two cells. The nuclei divide during a process called karyokinesis. The newly formed nuclei are in essence haploid, but the original cell is still intact and still has two full sets of chromosomes - albeit the sets are residing in different areas of the same cell. The cell divides into two cells shortly after Telophase I. Thi is called cytokinesis. At this point the new cells are certainly haploid. So the short answer is most definitely either anaphase I or telophase I. The stage that you choose will depend on the standards you use. Anaphase I will be the earliest by looking only at the nuclei. Telophase I will be the latest by looking only at the nuclei. Cytokinesis after Telophase I will be the latest. I am assuming that this is a question for a biology class. The key is to understand the difference between diploid and haploid and HOW they come about. Answering either Anaphase I or Telophase I should work IF you are able to support your answer by describing the process of Meiosis accurately.
Does the cell divide in two during mitosis?
No, because gametes do not divide. Specific cells called "germ cells" give rise to gametes through a process called meiosis. After that gametes do not divide again and simply wait until an opportunity arises in which they can pair up with their other gamete cell and form a zygote.
Why do gametes have half the number of chromosomes as somatic cells?
Since you need 46 chromosomes total to function properly, and each of your parents have 46 chromosomes, you need to get 23 chromosomes from each of your parents in order to have the correct number of 46 chromosomes. You get 22 somatic chromosomes (autosomes) and 1 sex chromosome from each parent. Of course, during oogenesis or spermatogenesis, there could be nondisjunction, resulting in you receiving more or less chromosomes than you should. An example of this is Down Syndrome, where you receive an extra copy of Chromosome 21 from either parent. However, generally you will only receive 23 chromosomes from each parent (through their gametes) so that when they combine, you will have the correct 46 chromosomes. That is why gametes (haploid) have half the number of chromosomes as somatic cells (diploid).
What had happen to the ploidy at the end of the process of mitosis?
At the end of mitosis two daughter cells are produced identical to the parent cell. If the parent cell is haploid the daughter cell will be haploid. If the parent cell is diploid the daughter cell is also diploid.
If the number of chromosomes in the skin cell of an organism is 28 what is the number of chromosomes in the organism's cells?
depends on the organism, but (i think) it should be half the normal number of chromosomes in a normal cell, because the gametes (egg and sperm) are haploid cells, meaning they have half the number because when they fuse together in fertilisation they need to have the correct amount of chromosomes so that they can duplicate and grow into an embryo.
