WebJul 8, 2024 · Gametes are specialized sex cells that contain half the number of chromosomes of the parent. In humans, the female gamete is called an ovum or egg, while the male gamete is called the sperm. Human development begins at fertilization – a process in which a sperm and an egg unite to form a single cell, called the zygote. WebGamete cells, also known as sex cells, are the cells responsible for sexual reproduction. A male gamete is called sperm (spermatozoa) and is a haploid cell formed through …
