查询词典 haploid

As a result, by the developmental stage of trochophore, most hybrids still had the karyotype of 2n=3m+5sm+15st+12t, according with theoretical expectation of hybrids, which crediblely proved to be a combination of haploid genomes of biparents in hybrids.

我们可以下这样的定论，大多数子代的担轮幼虫的染色体构成仍然符合理论预期型(2n=3m+5sm+15st+12t)，即其基因组染色体是由亲本扇贝的单套基因组染色体构成的，子代分别继承了母本和父本各一套染色体。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

它是单细胞真菌，有单倍体和二倍体两种存在形态。
