查询词典 epistasis

These were controlled by multiple allels or by loci with allels that segregate independently whereby epistasis also may have played a role.

这些是受复等位基因或含分离等位基因的位点支配的，上位性也可能靠它而起了作用。

QTL with relatively high magnitude of effects might also be involved in epistasis.

F_1、F_2和F_3株高的中亲优势和超亲优势基本上均为负方向，株高优势到了F_2已趋于稳定，且明显低于亲本。

"Epistasis:an interaction between nonallelic genes, especially an interaction in which one gene suppress es the expression of another."

异位显性：非等位基因的相互作用，尤其是一个基因对另一个基因所表现的显性现象。

However, only 4 of the loci involved had single-locus effects, indicating the complexity of epistasis and their important contributions to yield and yield component traits.

共检测到17对QTL加性和环境互作，以及14对上位性QTL与环境的互作，表明环境因素对产量和产量构成因子性状起重要影响作用。

Comparatively,epistasis as a genetic factor would be more important than main-effects of QTL for seedling vigor in rice.

如CRSV-6上的位点，不仅与CRSV-1上的位点互作影响7 d、11 d发芽率和芽长，还与CRSV-5上的位点互作影响7 d、9 d发芽率和芽长，同时也与第7染色体RM10-N16080区间的1个位点互作影响7 d发芽率。

Researches on drosophila, mice and yeast also suggested that epistasis between nuclear and mitochondria affected significantly the phenotype of offspring.

细胞质效应在动植物中广泛存在，在模式生物果蝇、小鼠和酵母上的研究表明，细胞质与细胞核间的上位性互作效应对后代有明显的影响。

Comparatively, epistasis as a genetic factor would be more important than main-effects of QTLs for seedling vigor in rice.

如CRSV-6上的位点，不仅与CRSV-1上的位点互作影响7 d、11 d发芽率和芽长，还与CRSV-5上的位点互作影响7 d、9 d发芽率和芽长，同时也与第7染色体RM10-N16080区间的1个位点互作影响7 d发芽率。

These results are in agreement with previous results for heading date in rice,and the results provide further information.which indicate that both epistasis and QE interaction are important genetic basis for determining heading date in rice.

对水稻抽穗期QTL的定位结果与前人研究基本一致，并进一步证实了上位性和QE互作效应是水稻抽穗期的重要遗传基础。

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。
