Ploidy - Wikipedia
The nucleus of a eukaryotic cell is haploid if it has a single set of chromosomes, each one not being part of a pair.By extension a cell may be called haploid if its nucleus is haploid, and an organism may be called haploid if its body cells (somatic cells) are haploid.
Haploid - Simple English Wikipedia, the free encyclopedia
Haploid is the term used when a cell has half the usual number of chromosomes.A normal eukaryotic organism is composed of diploid cells, one set of chromosomes from each parent. However, after meiosis, the number of chromosomes in gametes is halved. That is the haploid condition. In humans, the diploid number of chromosomes is 46 (2x23).The number in haploid cells (sperm and eggs) is 23.

Chromosomes - Pull up Those Genes Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA.Segments of DNA in specific patterns are called genes.Your genes make you who you are.
Doubled haploidy - Wikipedia
A doubled haploid (DH) is a genotype formed when haploid cells undergo chromosome doubling. Artificial production of doubled haploids is important in plant breeding.. Haploid cells are produced from pollen or egg cells or from other cells of the gametophyte, then by induced or spontaneous chromosome doubling, a doubled haploid cell is produced, which can be grown into a doubled haploid plant.
Meiosis — bozemanscience
Paul Andersen explains how the process of meiosis produces variable gametes. He starts with a brief discussion of haploid and diploid cells. He compares and contrasts spermatogenesis and oogenesis.
Haploidie – Wikipedia
Von Haploidie (altgriechisch ἁπλόος haplóos, ‚einfach‘) wird gesprochen, wenn das Genom (Erbgut) einer (Eukaryoten-)Zelle oder eines Prokaryoten (z. B. eines Bakteriums) nur einfach vorhanden ist, also jedes Allel in jeweils nur einer einzigen Ausprägung vorkommt.. Typischerweise sind die Chromosomensätze von Eizellen (Oocyten) und Spermien (Spermatozoen) haploid; die beiden ...
