Definition of haploid in English:

haploid

adjective ˈhaplɔɪdˈhæpˌlɔɪd

Genetics

1(of a cell or nucleus) having a single set of unpaired chromosomes.
（细胞，细胞核）单倍体的。比较DIPLOID
Compare with diploid
Example sentencesExamples
- The number of linkage groups resolved agrees well with the cytologically determined haploid chromosome number of 21.
- Two of them are seen in a single haploid nucleus.
- Each basidiospore contains a recombinant haploid nucleus, the product of meiosis.
- The FB-MOs, mitochondria, and haploid nuclei all segregate into budding spermatids and eventually occupy most of the cytoplasmic space.
- The computer keeps track of each mutation's position and deleterious effect on a single haploid chromosome for each individual.
1. 1.1 (of an organism or part) composed of haploid cells.
  （生物体或器官）由单倍体细胞构成的
  in mosses, the conspicuous leafy structures are haploid
  Example sentencesExamples
  Most of the remaining plants regenerated are sterile haploid plants while a few partially sterile plants could be polyploid or aneuploid.
  We conclude that Dempster's 1955 discrete-time model is irrelevant to the vast majority of haploid species subject to density-dependent population regulation.
  They differ from the ‘green algae’ in that the young sporophyte - or diploid plant - begins its development within the tissues of its parent gametophyte - or haploid plant.
  Two of the haploid plants generated from Fuyu 3xWMR 29 crosses were susceptible to races 1, 6, and 7.
  Due to the colchicine-induced or spontaneous process of chromosome doubling that takes place during the early stages of embryo development, fertile double haploid plants can be easily regenerated within a short period of time.

noun ˈhaplɔɪdˈhæpˌlɔɪd

Genetics

A haploid organism or cell.
单倍体生物（或细胞）
Example sentencesExamples
- Meiosis is the program used by sexually reproducing organisms to produce haploids from diploid precursors.
- The next two sections illustrate how to do this by carrying out the calculations for autosomal genes in dioecious haploids and for autosomal, sex-linked, and cytoplasmic genes in diploids.
- The number of recombinants and total cells for haploids was corrected to reflect the entire culture.
- This is likely to be the null phenotype for pob3 mutants since we observed a similar accumulation of cells after germination of haploids carrying a deletion of POB3.
- First, tetraploids continue to bud in stationary phase, whereas haploids arrest as unbudded cells.

Derivatives

haploidy

noun

Genetics

Although triploidy and haploidy of chromosomal regions in humans often cause viable or semiviable developmental defects, it is difficult to identify regions of the genome that are haplolethal.
Example sentencesExamples
- The problem was obvious: if the sex of an animal was the result of a balance of male- and female-determining genes on the sex chromosomes and autosomes, how could haploidy give rise to males?
- If deleterious mutations tend to be partially recessive, purifying selection is expected to be more efficient on the X chromosome relative to the autosomes, due to haploidy in males.
- Whether or not any particular deletion can be recovered will, of course, depend upon the phenotypic consequences of haploidy for its chromosome region.
- One possibility is that natural selection is more efficient on the X chromosome due to effective haploidy of the X chromosomes in males and persistently low effective numbers of reproducing males compared to that of females.

Origin

Early 20th century: from Greek haploos 'single' + -oid.
