When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing.

WebOne sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm, which serves as a source of nutrition for the developing embryo. Together, these two fertilization events in angiosperms are known as double fertilization, illustrated below. WebThe sperm and egg cells each possess specific features that make this process possible: The egg is the largest cell produced in most animals species. A human egg cell is approximately 16 times larger than a human sperm cell. The eggs of different species contain varying amounts of yolk, nutrients to support growth of the developing embryo.
