homologous chromosomes 中文意思是什麼

homologous chromosomes 解釋
同染色體
  • homologous : adj. 1. 同源的。2. 【生物學】異體同型的。3. 【化學】同系列的；同屬列的；同周期的。4. 【醫學】同源的。5. 【醫學】＝ homoplastic.
  • chromosomes : 第十八章 染色體
  1. Each of the 46 chromosomes is a member of a homologous pair.

    46條染色體的每一條都是一個同源對的成員。
  2. During diakinesis the sister chromatids of homologous pairs of chromosomes complete their separation, and the chromosomes coil tightly, shortening and thickening

    在終變期配對的同源染色體中的姐妹染色單體完成分離，染色體變成緊密凝集的狀態，縮至最小長度。
  3. Cross-overs have occurred independently of each other between pair of homologous chromosomes.

    交換現象獨立地在每一對同源染色體之間發生。
  4. Bivalent describing any pair of homologous chromosomes when they pair up during meiosis

    二價染色體：在減數分裂中配對時的任意一對同源染色體。
  5. Aneuploidy the condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number

    非整倍性：在減數分裂的過程中同源染色體不分離而造成的一條或多條染色體的缺失或增加。
  6. If both of a pair of homologous chromosomes are missing, nullisomy results

    如果一對同源染色體都缺失了，稱為缺體。
  7. Homologous chromosomes have chromomeres in identical places along their length

    同源染色體在相同的部位具有染色粒。
  8. Pachytene in meiosis, the stage in mid - prophase that is characterized by the contraction of paired homologous chromosomes

    粗線期：減數第一次分裂前中期中的一個階段，以配對同源染色體濃縮為特徵。
  9. Locus ( pl. loci ) the position of a gene on a chromosome. alleles of the same gene occupy the equivalent locus on homologous chromosomes

    基因位點，基因座：基因在染色體上的位置。等位基因位於同源染色體相對應的位點上。
  10. Synapsis ( pairing ) the association of homologous chromosomes during the prophase stage of meiosis that leads to the production of a haploid number of bivalents

    聯會（配對） ：能產生單倍二價體的減數分裂前期，同源染色體的聯合現象。
  11. Segregation the separation of the two alleles of a gene into different gametes, brought about by the separation of homologous chromosomes at anaphase 1 of meiosis

    分離：同源染色體在細胞減數分裂後期中向細胞極遷移，使等位基因最終分向不同配子。
  12. This usually takes the form of drawings or photographs of the individual chromosomes, often arranged in homologous pairs in numerical sequence

    通常採用對單個染色體描繪和拍照的形式將其配對排列。
  13. It is due to the lack of homologous pairs of chromosomes, so chromosomes cannot pair in meiosis, and the resulting gametes may have extra or missing chromosomes

    這歸因於染色體同系對的缺乏，以至於在減數分裂中染色體不能配對，導致配子有可能有額外或缺失染色體。
  14. Pairing of homologous chromosomes ( synapsis ) commences at one or several points on the chromosome and is clearly seen during pachytene of meiosis i

    同源染色體兩兩成對平行靠攏，這一現象也稱聯會，聯會發生在染色體的一點或多點上，可以在減數第一次分裂的粗線期觀察到。
