查询词典 haploid

Plants also differ from fungi in having a regular alternation of diploid and haploid generations.

植物与真菌的区别还在于植物具有规律性的世代交替。

In plants and algae that undergo alternation of generations, a gametophyte is the multicellular structure, or phase, that is haploid, containing a single set of chromosomes, and has its own information on genetic expression.

异型世代：具有典型的单倍体和二倍体世代交替的生活史的现象。

In organisms showing ALTERNATION OF GENERATIONS, the gametes may be produced by mitosis in the haploid generation, or by meiosis in the diploid generation and give rise directly to gametes or gamete-producing cells.

在表现出明显世代交替的生物体中，配子可能是由单倍体世代发生有丝分裂产生，亦可由二倍体世代减数分裂直接产生配子体或配子母细胞。

Aneuploid describes chromosome numbers which are not multiples of the haploid number.

非整倍体所描述是单倍体数目并非成倍增加。

SSR analysis indicated that triploids were derived from nucellar apomixis; diploids were most probably from sexual crosses of haploid female gametes and alien pollen grains.

SSR分析结果表明三倍体后代来源於柑橘珠心细胞的无融合生殖，而二倍体个体很可能是单倍体的雌配子与外界花粉杂交后代。

Part one: Previous results indicated that the abnormal development of haploid goldfish embryos is due to the expression obstruction of some proteins, which are correlative with eyes development, nerve development, development regulation, cell differentiation and maintenance, arthromere formation and signal transduction.

第一部分金鱼雌核发育过程中胚胎蛋白质组比较研究前期已发表的工作表明在金鱼雌核发育眼睛形成期(受精后26个小时)单倍体上一些与眼睛发育、神经发育、发育调控等相关的重要蛋白质未能被选择表达或表达受阻，从而导致单倍体发育畸形。

Haploid were obtained through spore culture and spore separation text of Saccharomyces uvarum diploid M-3 that can utilize the melibiose. One haploid with good quality was screened as the parent for the hybridization.

In mixoploid plants, somatic cells with 2n=25~29 were most frequent except for a few haploid cells (2n=19) and chromosome doubling cells (2n=50~60). Abnormal chromosome behaviors were observed in pollen mother cells from mixoploid BI-1 and haploid, including chromosome bridges, laggard chromosomes, meiotic cycle asynchrony and unequal separation of chromosomes.

对混倍体植株BI-1和单倍体植株的花粉母细胞(Pollen mother cells，PMCs)减数分裂染色体行为观察发现，高频率出现染色体落后、染色体桥、染色体分裂周期不同步、不均等分离等异常染色体行为。
