Use in clinical context
Gametes are formed through the process of meiosis. Meiosis has two stages of cell division, termed meiosis one and meiosis two. Secondary gametes are formed at the end of meiosis two, the final part of meiosis.
Each resulting gamete is haploid, it contains a single copy of each chromosome. Any variants that have been introduced during meiosis may be present in the gametes which may result in a different phenotype, including those affecting health, should the gamete reach fertilisation.
