Fertilization is internal in humans i.e. zygote is formed and developed inside the body of a female in a fallopian tube. During sexual intercourse, millions of sperms are ejaculated and about a few hundreds of them will reach the ovum in the fallopian tube. The first stage is the penetrati...
Since both male and female sex cells are haploid, meaning they contain half the number of chromosomes as other somatic cells (23 in humans), their fusion restores the diploid number of chromosomes (46 in humans). After the formation of zygotes, two prominent bodies, the male pronucleus and...
We then studied human 1PN zygotes and found that the HIRA complex was absent in 1PN zygotes that lacked the male pronucleus. This shows that the role of the HIRA complex in male pronucleus formation potentially has coherence from mice to humans. Furthermore, rescue experiments in mouse ...
In humans, how many chromosomes are in each cell after mitosis? How many pairs of chromosomes are normally in each cell of the human body? How many chromosomes are in a human somatic cell? How many gametes do humans have in their somatic cells?

Also, their ability to proliferate continuously can lead to the formation of tumors postimplantation [56], a major concern when transplanting these cells in patients. Many of the original human embryonic stem cell lines were derived in the presence of animal products such as fetal bovine serum ...
While the terminology which surrounds developing organisms at various states of development is highly scientific and clearly defined, beliefs about when life begins are a bit more complex. Some people believe that the formation of a zygote represents the beginning of life, and that the single cell...
An international journal dedicated to the rapid publication of original research in early embryology, Zygote covers interdisciplinary studies on gametogenesis through fertilization to gastrulation in animals and humans. The scope has been expanded to include clinical papers, molecular and developmental ...
