diploid

diploid somatic cells.

二倍细胞

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

二倍物：代表活史中植物阶段的二倍物，其单倍仅局限于配子。

*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、二倍、21、四和六)；

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. "

有些类是大家都很熟悉的，比如硬粒小麦、二粒小麦、波兰小麦、圆锥小麦。它们都是四倍。此外还有一粒小麦，是二倍。

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，此在二倍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.

对植物染色工程与双二倍、异附加系、异代换系、易位系、单与缺系统进行了综述。

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，在二倍水平上选育水稻无融和殖种质的难度较大，而在多倍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。
