Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. This condition is called ‘anisogamy’ or ‘heterogamy’, wherein the female and male gametes are of different sizes (in the case of humans, the ovum is ~20 times larger than the sperm cell).

Human gametes contain 23 chromosomes, one of each. Here we'll focus on diploid cells (humans have diploid cells), which contain two slightly different

There are male gametes called sperms and female gametes called ova. 50% sperms contain X Human cells contain 46 chromosomes - 22 pairs of homologous autosomes and one pair of Haploid gametes unite at fertilization to create a diploid zygote. Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad. In humans, 2n = 46, and n = 23.

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.
