The terms male and female typically do not use in sexually undifferentiated species in which the individuals are isomorphic (look the similar) and the gametes are isogamous (indistinguishable in size and form), these as the eco-friendly alga Ulva lactuca. In either case, gametes may be externally identical (isogamy) as in the inexperienced alga Ulva or may possibly be distinct in size and other areas (anisogamy). The dimension distinction is biggest in oogamy, a variety of anisogamy in which a modest, motile gamete brings together with a significantly larger, non-motile gamete.

By conference, the larger sized gamete (referred to as an ovum, or egg mobile) is deemed female, whilst the smaller gamete (referred to as a spermatozoon, or sperm cell) is regarded as male. Male plants and animals make lesser gametes (spermatozoa, sperm) whilst women create larger sized types (ova, normally called egg cells). In vegetation, the diploid organism creates haploid spores by meiosis that are able of undergoing repeated mobile division to generate multicellular haploid organisms. In animals, the haploid phase only occurs in the gametes, the haploid cells that are specialised to fuse to form a zygote that develops into a new diploid organism.
The cells of eukaryotes have a set of paired homologous chromosomes, one particular from just about every dad or mum, and this double-chromosome phase is termed «diploid». The mixture of chromosomal crossover and fertilization, bringing the two single sets of chromosomes collectively to make a new diploid zygote, results in new organisms that incorporate unique sets of the genetic attributes of each and every guardian. Then the chromosomes are separated into single sets in the gametes.
