In eukaryotes, haploid gametes are produced by meiosis; two gametes fuse to form a diploid zygote. Eukaryotes have a life cycle that involves sexual reproduction , alternating between a haploid phase, where only one copy of each chromosome is present in each cell and a diploid phase, with two copies of … See more Eukaryota or Eukarya, whose members are known as eukaryotes , is a diverse domain of organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms are eukaryotes. They … See more Cells The defining feature of eukaryotes is that their cells have a nucleus.

During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores (Figure 7.1. 1 b ).
