WebFeb 28, 2024 · In addition, the use of postmortem collected gametes for research is more cost-effective. Unfortunately, the infield application of gametes collected postmortem is limited due to the decrease in quality of the gametes over time, which results in lower blastocyst rates compared to gametes derived from living animals [62,141]. WebA zygote (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. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism.
