explain zygote formation in human beings
Answers
Answer:
Fertilization is the fusion of two haploid gametes to produce a diploid zygote. Each haploid gamete in humans has 23 chromosomes, while the diploid zygote has 46. This fusion usually occurs within 24 hours after the oocyte has been released from the ovary. ... Then, they have to break through the oocyte's defenses.
A zygote is a eukaryotic cell formed by a fertilization event between two gametes. 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. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring.
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.
What Happens to a Zygote Following Fertilization? A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. ... In humans, it takes about four days for a zygote to become a morula and another three days until the embryo attaches itself to the mother's uterine wall.
