a cell formed as a result of the fusion of gametes. The term “zygote” was introduced by the German botanist E. Strassburger. As distinct from gametes, a zygote has a diploid (double) set of chromosomes. The zygote develops directly after fertilization or, as in many algae and fungi, takes on a thick covering and becomes a dormant spore, often called a zygospore, for some time.
