	The Haploid Life Cycle
		Haploid life cycle is the most common in algae (without dikaryotic phase) and most fungi (with dikaryotic phase).
		Colonial alga such as red alga, brown alga, and green alga and filamentous alga such as red, green, and brown alga all exhibit haploid life cycle.
		A general life history includes both a 1n stage and a 2n stage separated by meiosis and syngamy.

	Haploid Cells
		Haploid cells are often used in sexual reproduction.
		In fungus and certain algae, however, haploid cells are the norm.
		Haploid cells in animals are formed through meiosis, where one chromosome is chosen at random to inhabit the haploid germ cells.

	Meiosis
		Haploid cells are then formed, each a genetic form intermediate between that of each of its parent's two parents.
		Finally, this haploid cell may fuse (fertilization) with a haploid cell sourced from a second individual, so long as that second individual is not of the same gender (and appropriate and timely intimacy has been achieved).
		That is, the two haploid cells which are the products of meiosis II are not identical (as too the two cells which were the product of meiosis I were not identical--in mitosis occurring among haploid cells this would not be the case).

	Wikinfo \| Haploid
		Haploid cells have only one copy of each chromosome.
		Within higher organisms, only the reproductive cells are haploid, whereas the somatic (body) cells are diploid (two copies of each chromosome) or polyploid (three or more copies of each chromosome, often found in plants).
		When reproducing, the haploid sex cells of both parents will generally merge to form a diploid cell the zygote, with unique genetic properties, which will quickly become the embryo.

	Haploid Embryogenesis (Site not responding. Last check: )
		The cells of gamete-producing tissue of conifers is haploid, having half the chromosome complement of the sporophyte.
		In conifers, it is only possible to induce haploid embryos from female tissue, in particular, the prothallial cells of the megagametophyte.
		The plants that arise from such cultures are initially stably haploid, but soon develop mixoploid regions, in which tracts of cells with double the chromosome number are found.
