同源染色体带纹的数目、大小和分布基本一致。
Bands stripes in homologous chromosomes are similar in their number, size and distribution.
端粒克隆、着丝粒克隆以及重叠群之间空缺的大小都经过粗线期染色体荧光原位杂交鉴定。
BAC clones corresponding to telomeres, as well as to the centromere position and the gap sizes between contigs, were determined by BAC-pachytene chromosome fluorescence in situ hybridization (FISH).
虽然这些物种都是二倍体并且含有相同数量的染色体但是杂交体和亲本间核基因组大小仍不相同。
The nuclear-genome size differences between the hybrids and their parental taxa occur in spite of the fact that all species possess the same number of chromosomes and are diploids.
结果表明，花冠大小与染色体倍性密切相关。
We found that corolla size is highly correlated with ploidy level.
由于不同物种的染色体数目、大小和形状有很大区别并且具有稳定性，因此核型可以为某一物种的特征。
A species can be characterized by its karyotype since the number, size, and shape of chromosomes vary greatly between species but are fairly constant within species.
在各染色体相对长度，C带的大小，位置和着色程度上又存在不同程度的差异，可以作为区分种的依据。
There are some differences in the relative length of chromosomes and in the size, location and degree of dyeing of C-bands between the 2 species. This could be used to distinguish species.
染色体倍性提高，气孔保卫细胞的大小及其中叶绿粒数目增加，而气孔器密度减小。
With the increase of chromosome ploidy, the size of stomatal guard cells and the chloroplastid Numbers were increased, accompanied by the decrement of stomatal density.
