(of a nucleus, cell, or organism) having an exact multiple of the haploid number of chromosomes.
- ‘The pilot study shows that in vitro grown and matured oocytes from preantral follicles that progress to metaphase II possess euploid numbers of chromosomes.’
- ‘First, of the population of tetraploid cells that enter stationary phase, both euploid and aneuploid members can be rescued by starvation in water.’
- ‘Aneuploid pollen grains compete poorly with euploid pollen and so aneuploidies are eliminated when propagated through the male.’
- ‘When colonies are formed, the resulting cells tend to have euploid genomes derived from the aneuploid state by chromosome loss.’
- ‘Within both groups, many plants possessed a genome content that deviated from the euploid parents by at least the approximate size of one chromosome.’
Early 20th century: from eu- + -oid as in diploid, haploid.
