Adults humans produce haploid gametes (sperm and ova) be meiosis in the testes and ovaries.
After sexual intercourse, fertilisation is the joining of one sperm and one ovum to form the diploid zygote. The zygote then divides by mitosis to grow into a new human about 40 weeks later.
19.
Meiosis may be occurring with the production of gametes in gonads.
Mitosis is occurring in all body organs as new cells are made. The only exception to the prolific regrowth of new cells is the nervous system.
20.
Crossing over and recombination may occur during meiosis when parts of homologous chromosomes break and rejoin, so that combinations of genes in the offspring were not present in the parents.
