The gametic or haploid number (n) is the number of chromosomes in a gamete. Two gametes form a diploid zygote with twice this number (2 n, the zygotic or diploid number) i.e. two copies of autosomal chromosomes. For humans, a diploid species, n = 23. A typical human somatic cell contains 46 chromosomes: 2 complete haploid sets, which make up 23 homologous chromosome pairs.  From Zygote to the Adult. The zygote divides to form two, new cells. The nucleus of the zygote undergoes mitosis to distribute equal copies of chromatin to the two new nuclei, of which one each is in one of the two new cells. Each new cell contains a nucleus with the 2n number of chromosomes. Those two cells divide to form four cells, each of the 4 cells contains the 2n number of chromosomes. Cell divisions occur repeatedly, and eventually there are millions of cells in the organism. A zygote contains two sets of chromosomes, which is represented by 2n. One set of chromosomes came from the egg, and the other set from the sperm. The term for a cell that contains the 2n number of chromosomes is diploid. Diploid also is used as an adjective for an organism that consists of diploid cells Humans Edit. In human fertilization, two 1n haploid cells—an ovum (female gamete) and a sperm cell (male gamete)—combine to form a single 2n diploid cell called the zygote. DNA is then replicated in the two separate pronuclei derived from the sperm and ovum, making the zygote's chromosome number temporarily 4n diploid. After approximately 30 hours, fusion of the pronuclei and subsequent mitotic division produce two 2n diploid daughter cells called blastomeres. In fungi, the sexual fusion of haploid cells is called karyogamy. The result of karyogamy is a diploid cell called a zygote or zygospore. This cell may then enter meiosis or mitosis depending on the life cycle of the species. DNA is then replicated in the two separate pronuclei derived from the sperm and ovum, making the zygote's chromosome number temporarily 4n diploid. After approximately 30 hours, fusion of the pronuclei and subsequent mitotic division produce two 2n diploid daughter cells called blastomeres. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual. In multicellular organisms, the zygote is the earliest developmental stage. DNA is then replicated in the two separate pronuclei derived from the sperm and ovum, making the zygote's chromosome number temporarily 4n diploid. After approximately 30 hours, fusion of the pronuclei and subsequent mitotic division produce two 2n diploid daughter cells called blastomeres. Two single sets of pairs (daughter) chromosomes are formed by separation of the pair of chromatids during cell division (from anaphase on in mitosis and anaphase II in meiosis). Haploid is the term for a cell or an organism with only one set of chromosomes (n). Each chromosome consists of two chromatids. Diploid is the term for cells with a double number of chromosomes (2n), whereby one set of chromosomes is homolog to the other. (The sex chromosomes present in each human cell are an exception). Chromatid are the two sister sides of a chromosome that are identical to each other and contain the same genetic information. The chromosomes split in half during mitosis (or meiosis in sex cells) and each new daughter cell gets one chromatid. The chromosome number of a fertilized egg will always be calculated by the formula 2n. n signifies the haploid number, and 2n is the diploid number. The number of chromosomes in a human gamete is zygote-originating from the haploid number 23 in the gamete. This depends on the species of the egg. The ovum, and therefore the zygote, is much larger than a normal cell. The zygote contains one set of chromosomes from each gamete; so it has all the genetic information encoded in it for development. However, the genes are not immediately activated to produce proteins. First, the zygote undergoes mitotic cell division several times. Humans have 23 pairs of chromosomes; 46 chromosomes in all, 23 from the father and 23 from the mother.A normal human being has 23 chromosomes from each parent, giving them 23 pairs or 46 in total. It is called Haploid. The chromosome number of a fertilized egg will always be calculated by the formula 2n. n signifies the haploid number, and 2n is the diploid number. The number of chromosomes in a human gamete is zygote-originating from the haploid number 23 in the gamete. This depends on the species of the egg.
