A zygote (/ ˈ z aɪ ˌ ɡ oʊ t /; from Ancient Greek ζυγωτός (zygōtós) ' joined, yoked ', from ζυγοῦν (zygoun) ' to join, to yoke ') [1] is a eukaryotic cell formed by a fertilization event between two gametes.

After fertilisation the zygote has two copies of each of the chromosomes (not worrying about sex chromosomes). When each of these is replicated the cells will have chromosome pairs, which will then divide in mitosis.

Mar 3, 2025 · zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Oct 15, 2024 · A zygote is a single cell that’s the result of one egg and one sperm combining their genetic material, resulting in 23 pairs of chromosomes, says NIH. How Does a Zygote Form? When egg meets sperm (called fertilization), 23 chromosomes from the egg match up with 23 chromosomes from the sperm.

Feb 2, 2024 · A zygote is the very first form your baby takes – before they're even in the womb. Read on to find out how and when a zygote forms and how, if all goes well, it will become a blastocyst, embryo, fetus, and then baby.

Jun 2, 2024 · A zygote is the simplest form of life, so once a zygote is formed, it proceeds to split and divide into new cells that organize and form more complex structures. Around 30 hours after the zygote is formed, the process of mitosis (cell division) begins…

Oct 10, 2023 · A zygote, also called a fertilized egg, is the phase of conception where the egg and sperm join to form a single cell. The zygote contains a full set of chromosomes, with 23 from the egg and 23 from the sperm.

4 days ago · The zygote is the first diploid cell that forms following fertilization by fusion of the haploid oocyte (egg) and spermatozoa (sperm) resulting in the combination of their separate genomes.

Formation of the zygote. At puberty cells in the gonads (testis or ovaries) undergo meiosis. 23 pairs of homologous chromosomes become 23 chromosomes. The germ cell from the male (sperm) will then fuse with the germ cell of the female (ovum) during reproduction to reform a cell with 23 pairs of homologous chromosomes.

A zygote is the initial cell produced through reproduction in humans and most other organisms. From the Greek word meaning to join or to yoke, a zygote is a single cell made by the fertilization, either naturally or artificially, of the female gamete (ovum or egg) by the male gamete (sperm).
