Germ cells are specialized cells responsible for producing gametes, which are the reproductive cells in organisms. In humans and many animals, germ cells develop into sperm in males and eggs in females. These cells carry half the genetic information needed for the formation of a new individual, ensuring genetic diversity through sexual reproduction. During the process of meiosis, germ cells undergo division to reduce their chromosome number by half. This is crucial for maintaining the correct number of chromosomes in offspring when sperm and egg unite during fertilization. Germ cells originate from the embryonic stage and are essential for the continuation of a species.
