Haploidisation is the process of halving the chromosomal content of a cell, producing a haploid cell. Within the normal reproductive cycle, haploidisation is one of the major functional consequences of meiosis, the other being a process of chromosomal crossover that mingles the genetic content of the parental chromosomes. [1]
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.
Karyogamy in the context of cell fusion. 1-haploid cells, 2-cell fusion, 3-single cell with two pronuclei, 4-fusing pronuclei (karyogamy), 5-diploid cell Karyogamy is the final step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei .
The parasexual cycle, a process restricted to fungi and single-celled organisms, is a nonsexual mechanism of parasexuality for transferring genetic material without meiosis or the development of sexual structures. [1]
The Spanish Wikipedia (Spanish: Wikipedia en español) is the Spanish-language edition of Wikipedia, a free online encyclopedia. It has 2,009,807 articles. It has 2,009,807 articles. Started in May 2001, it reached 100,000 articles on 8 March 2006, and 1,000,000 articles on 16 May 2013.
The Enciclopedia Libre was founded by contributors to the Spanish Wikipedia who decided to start an independent project. Led by Edgar Enyedy, they left Wikipedia on 26 February 2002, and created the new website, provided by the University of Seville for free, with the freely licensed articles of the Spanish Wikipedia.

This is a list of television programs currently broadcast (in first-run or reruns), scheduled to be broadcast, or formerly broadcast on Discovery Kids, a Latin American cable television channel owned by Warner Bros. Discovery.
Canal Once launched Once Niños as its first digital subchannel on August 24, 2015. [2] The channel would serve as an extension of the main channel's original children's programming for children between the ages of four and twelve; overnight, between midnight and 6am, it would not air programming, but instead an image inviting kids to go to sleep.
