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]. WebThis process is similar to production of gametes in animals (note that haploid gametes in plants are produced by mitosis from a haploid gametophyte). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther where they have the opportunity to be transported to stigmas by wind, water, or an animal pollinator.
