diploid

diploid somatic cells.

二体细胞

Diplont A diploid organism that represents the vegetative stage in life cycles in which haploidy is restricted to the gametes.

二体物：代表活史中植物体阶段的二体物，其单体仅局限于配子体。

*X represents monosomy 21,diploid,trisomy 21,tetrasonmy 21 and hexasomy 21 in the corresponding box.

(X代表相应栏中的21单体、二体、21三体、四体和六体)；

1. "Some of the well-known types are the durum, emmet , Polish, and poulard. These are tetraploids. and there is the einkorn, which is a diploid. "

有些类型是大家都很熟悉的，比如硬粒、二粒、波兰、圆。它们都是四体。此外还有一粒，是二体。

hemizygous Describing genetic material that has no homologous counterpart and is thus unpaired in the diploid state.

半合子的：是一类没有同源配对物的，因此在二体中不成对的遗传物质。

This paper reviewed the chromosomal engineering in the aspects of double diploid, hetero-additive line, hetero-replacement line, exchange line, monosome one incomplete chromosome systems.

对植物色体工程与双二体、异附加系、异代换系、易位系、单体与缺体系统进行了综述。

Abstract : It is difficulty to select and breed apomictic germplasm among diploid rices at present, but it has become a hotspot to select and breed apomictic germplasm among polyploid rices.

摘要 ： 目前，在二体水平上选育水稻无融和殖种质的难度较大，而在多体水平筛选水稻无融和殖新种质已成为水稻无融和殖研究新的长点。
