0 having two sets of chromosomes (= structures containing chemical patterns that control what a plant or animal is like), one from each parent -- 二倍的，二倍體的（具有兩套分別來自父體和母體的染色體）
a diploid cell 二倍體細胞
Whatever the dominance coefficient, this differs from the continuous decrease of inbreeding depression with the selfing rate in diploids.
Effect of excluding sib matings on inbreeding coefficient and effective size of finite diploid populations.
The second series of experiments was designed to test the effects of ploidy and involved aggregating a big diploid cell with a big tetraploid cell.
Therefore, untreated and refractory diploids were pooled in tests to determine any effects of ploidy status.
Sorting out might also occur in big tetraploidbig diploid chimaeras if tetraploid and diploid cells had different cell surface properties.
Heritability estimates were obtained assuming a diploid inheritance model without epistasis and noninbred parents chosen at random from the parent varieties.
No major differences were observed for the two indices between the two diploid or the two triploid populations.
This implies that diploid individuals tend to ' mask ' deleterious mutations with ' normal ' alleles carried on the homologous chromosomes.
