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 gamete 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 ovum) is 23.
Haploid | Define Haploid at Dictionary.com
Having the same number of sets of chromosomes as a germ cell, or half the diploid number of a somatic cell. The haploid number (23 in humans) is the normal chromosome complement of germ cells.

By rapidly screening many of them, the researchers could isolate cells that stayed haploid after division — about 1 in 1,000. — Jonathon Keats, Discover Magazine, "Lab Divides Human Egg Cells," 19 Dec. 2016 In 2001, Dr. Gianpiero Palermo of the Weill Medical College at Cornell University in New York announced that his team created artificially haploid eggs by ...

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.
Diploid vs Haploid - Difference and Comparison | Diffen
During the process of reproduction, haploid cells (male and female) unite to form a diploid zygote. Cell growth is the result of mitosis; it is a process by which mother cells divide to give rise to identical daughter cells with equal number of chromosomes.
Diploid vs Haploid — bozemanscience
In this video Paul Andersen explains the difference between diploid and haploid cells. He starts with a brief description of the central dogma and how genes code for proteins.
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.

Syngenta scientists have solved the mystery behind an abnormal corn line responsible for revolutionizing corn breeding. Discovered in 1959 by University of Missouri Professor Edward H. Coe, Ph.D., the line produces haploid plants that contain just half the DNA of normal corn.

dentary /DENT-er-ee/ n. One of the pair of bones present in the lower jaw of most vertebrates.. denticles /DENT-ə-kəls/ n. Small, sharp, toothlike scales found on sharks, rays and chimaeras. Unlike ordinary fish scales, denticles have a structure similar to that of real teeth (i.e., an internal pulp cavity surrounded by dentin with an enamel-like coat of vitrodentine).
