Bivalents

基本解釋

When synapsis is complete the paired chromosomes are referred to as bivalents.
當聯(lián)會完成的時候,那配成對的染色體叫做二價體。
The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
有時交叉可以從二價體末端處滑開，因此移端過程可以降低交叉頻率。
There were less bivalents at meiotic MI of PMC than expected,and no multivalent had been found.
在小孢子發(fā)育過程中，四分體期有多個微核出現(xiàn)，同時發(fā)生了高頻的多分孢子，形成五分、六分孢子；
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(lián)會（配對）：能產(chǎn)生單倍二價體的減數(shù)分裂前期，同源染色體的聯(lián)合現(xiàn)象。
Abstract:We have developed a technique of random-primed tritium labeled DNA extension on the pachytene bivalents of rice-field eels.
采用隨機引物,在黃鱔二價體上建立了氚標記引物原位DNA合成技術,并詳細探索了該技術的實驗條件。
