- Reduction of the diploid number of chromosomes by one half during meiosis,resulting in the haploid number. 减半作用在减数分裂过程中染色体双倍体数目的减半而导致其变成单倍体数目。
- Tetraploid A cell or organism containing four times the haploid number of chromosomes. 四倍体：具有四个的单倍染色体组的细胞或生物体。
- Tripoid A cell, tissue or organism containing three times the haploid number of chromosomes. 三倍体：具有三个单倍染色体组的细胞、组织或有机体。
- Synapsis (pairing) The association of homologous chromosomes during the prophase stage of meiosis that leads to the production of a haploid number of bivalents. 联会（配对）：能产生单倍二价体的减数分裂前期，同源染色体的联合现象。
- Euploidy The normal state in which an organism's chromosome number is an exact multiple of the haploid number characteristic of the species. 整倍性：正常状态下，生物体染色体数是此种生物单倍体数目整数倍的现象被称为整倍性。
- The processes by which gametes are formed, including the reduction of chromosomes in a germ cell from the diploid number to the haploid number by meiosis. 结合的过程配子形成过程，包括生殖细胞因成熟分裂造成其内铬酸由二倍体数减少到单倍体数的过程
- The processes by which gametes are formed,including the reduction of chromosomes in a germ cell from the diploid number to the haploid number by meiosis. 结合的过程配子形成过程，包括生殖细胞因成熟分裂造成其内铬酸由二倍体数减少到单倍体数的过程。
- A reproductive cell having the haploid number of chromosomes,especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg. 配子，具有染色体的单倍数的生殖细胞，尤指一个成熟精子或卵子能与相对性的配子结合而产生受精卵。
- A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg. 配子具有染色体的单倍数的生殖细胞，尤指一个成熟精子或卵子能与相对性的配子结合而产生受精卵
- Zygotene is characterized by the active and specific pairing(synapsis) of homologous chromosomes leading to the formation of a haploid number of bivalents. 偶线期时，以同源染色体活跃的、特定的配对（联会）为特征，形成了单倍数的二价染色体。
- A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg . 在哺乳动物中,卵与精子结合而成受精卵,受精卵发生数次细胞分裂(卵裂)后,形成一个中空球形的囊胚。
- Aneuploid describes chromosome numbers which are not multiples of the haploid number (n). 非整倍体所描述是单倍体数目（n）并非成倍增加。
- For example, if the haploid number is 7, the euploid number would be 7,14,21,28, etc, and there would be equal numbers of each different chromosome. 例如，一种生物单倍体染色体数目是7，整倍数将是7、14、21、28等数目，并且每条不同的染色体有相等的数目。
- Reduction division The first division of meiosis , including prophase, metaphase I, and anaphase I.It results in a haploid number of chromosomes gathering at each end of the nuclear spindle. 减数分裂：减数分裂中的第一次分裂，包括分裂前期，中期I和后期I，形成单倍数目的染色体在每一个核纺锤体末端聚集。
- He thumbed through the directory to look for her number. 他翻阅电话号码簿找寻她的号码。
