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.
研究进一步证明人工复合三倍体鲤与二倍体亲本的染色体倍性和相对dna含量存在着明显的相关性。
Therefore, we have proved that there is a close correlation between the artificial multiple triploid carp and its diploid parents in both chromosomal Numbers and relative DNA contents.
以外周血淋巴细胞制备染色体标本，人工复合三倍体鲤染色体数为150，其亲本红鲤、红鲫和散鳞镜鲤的二倍体染色体数均为100。
Chromosome preparations made from leucocyte cultures showed that the artificial multiple triploid carp has a chromosomal number of 150, and all the fore parental forms have 100.
第5染色体上的微效QT L源自籼稻亲本。
选用分布于水稻12条染色体上的40对SSR引物对6个杂交水稻组合及其亲本的幼苗进行了SSR等位基因多态性分析。
SSR allele polymorphism of 6 hybrids and their parents was studied by analysing 40 SSR loci distributing on 12 chromosomes in rice.
