父本

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 physical and mechanical properties of the hybrid tulip tree are firstly reported and analyzed in this paper.

摘 要：本文研究了杂种鹅掌楸木材的物理力学性质，并与其母本中国鹅掌楸和父本北美鹅掌楸木材的作了比较。

With longger perianth segment and Liriodendron tulipiferawith widder perianth segment. The length of fruit ahd number of little key fruits showed patroclinal transgressive inheritance, so Liriodendron interspecific hybrids with bigger fruit could be selected by Liriodendron tulipifera?

聚合果长度和聚合果具翅小坚果数表现为偏父超亲遗传，选用聚合果较长和聚合果具翅小坚果数目较多的的北美鹅掌楸作父本，有望选育出大果的杂交鹅掌楸个体，而且这两者呈显著正相关(r=0.888)。

A new line of fruit fly with 3 recessive characters(white-eye, winglet and ebony-body) was bred by means of crossing between the female with white-eye and winglet and the male with ebony-body.

以白眼小翅果蝇为母本、黑檀体果蝇为父本，通过杂交的方法，选育出了集白眼、小翅、黑檀体三隐性性状于一身的果蝇新品系。

Moreover,we reared about 20,000 androgenetic silkworms and succeeded in getting successors from androgenetic silkworms.

所有雄核发育蚕都为雄性，且只表现父本性状，不表现母本性状。

Parental lines were: female parent 3-2-2 from China, thin-skinned melon, monoecious; male parent TopMark, from USA, thick-skinned and netted melon, andromonoecious; tested parent WI998, from USA, netted melon, gynoecious.

本试验选择亲本材料分别为：母本3-2-2，来自中国，薄皮甜瓜，雌雄异花同株材料；父本TopMark，来源美国，厚皮网纹甜瓜，雄全同株材料；检验亲本：WI998，来源美国，网纹甜瓜，全雌株材料。

The results showed that the electrophoric patterns of isozymes of "allogynogenetic Crucian Carp" were the same as those of its female parent and significantly different from its male parent.

结果显示：异育淇鲫同工酶的电泳图谱与母本淇鲫相同，与父本兴国红鲤显著不同。

Twenty-four random primers were used to analyze the genomes of three descendant strains with steady hereditable variation produced form domesticated silkworm by artificial insemination with sperms of eri silkworm. The results show that in the RAPD patterns there are many amplified bands called" parental bands"which are similar to those of the female parent. At the same time, there appears varied amount of amplified bands called "variant bands" that are different from those of the female parent. The variant ...

采用24种随机引物，对以蓖麻蚕精子进行人工授精得到的家蚕后代中的3个稳定变异品系及其亲本的基因组进行了RAPD检测，结果显示，在变异品系的RAPD图谱中，不仅存在大量与母本相同的&亲本带&，同时还出现了不同数量与母本不同的&变异带&，包括&非亲本带&、&缺失带&及个别仅与父本相同的&目的带&，从分子水平上揭示了变异品系存在着明显的&偏母性&与&变异性&特点。

Two polymorphic loci, Aat-1 and Aat-2, and one monomorphic locus, Aat-3, were observed in C. hytivusparents and their progenies. At Aat-1, in C. sativus fast-migrating anodic band coded for Aat-1 (2), however, in C.

在Aat-1，新种父本表现为一条阳极快带，为等位基因Aat-1(2)所编码；新种母本则表现为一条阴极慢带，为等位基因Aat-1(1)所编码。

A mispairing PCR-RFLP technique was applied in this study to determine the Insulin-like Growth Factor 2(IGF2) gene intron3 G3072A mutation in an outbred Landrace and Large White, and the gelded boars from Landrace×Large White cross. The difference of corresponding traits and the genetic effects of the boars inherited from parental A allele and inherited from parental G allele were analyzed.

采用错配PCR-RFLP技术鉴别了长白猪和大白猪纯种以及长白×大白猪杂交后代去势公猪胰岛素样生长因子2(IGF2)基因内含子3的3072位点变异，分析了遗传来自父本不同等位基因个体间的相关性状差异及不同等位基因的遗传效应。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
