单倍体（haploid） Chromosome ploidy is the number of homologous chromosomes in a cell, in which only one group is known as single set or haploid. Note that there is a difference between a haploid and a diploid (an organism containing a single set of chromosomes). Some haploid organisms do not contain only one chromosome group in their somatic cells. The vast majority of biological diplont containing a group of haploid chromosome in somatic cells, if the original species of polyploid genome number, then it contains haploid cells in a more than one. If the haploid of tetraploid rice contains two chromosomes, the haploid of six times of wheat contains three chromosomes. Haploid pepper Directory definition English Name: Haploid Concept: the somatic chromosome number is the gamete chromosome of this species Definition explanation A cell or individual having gametes. An individual consisting of only half of the genomes of the original organism is called a haploid (D.F.I.Langlet, 1927). A half body equal to the number of chromosomes in an organisms body. The basic characters of it and although the original organism is same, but generally more and more small, delicate, plant haploid almost not formed. Because there is no homologous chromosome of haploid, so only univalent chromosomes in meiosis, which led to; but there are also all univalent chromosomes complete still keep moving to the pole, then you can function in the formation of gametes, produce seeds; but in most cases due to chromosome sub group of cells containing incomplete so, will become highly sterile. For example: there are 32 chromosomes of bee queen and worker of somatic cells, and a somatic cell only 16 chromosomes, such as male gametes of this species, somatic cell containing individual chromosome number, called haploid. But some haploid organisms do not contain only one genome in their somatic cells Breeders commonly used anther in vitro culture methods to obtain haploid plants, and then after artificial induct
