Freckles are a genetic trait most comonly found in individuals with lighter complexions and /or fair or red hair.

雀斑是一种遗传性状最comonly发现，在个人与打火机complexions和/或公平或红色头发。

Seventeen genotypes of soft wheat were sown in three locations for two years to study the genetic variation of the water-soluble pentosans, water-insoluble pentosans, and total pentosans, to investigate the effects of genotype, environment and their interaction on pentosans, and to determine the relationships between pentosans and other quality parameters.

将17份软质小麦品种进行了两年多点试验，分析了水溶性戊聚糖、非水溶性戊聚糖和总戊聚糖含量的遗传变异和基因型、环境及其互作对其影响；同时研究了3种戊聚糖含量与其它品质性状的关系。

To estimate the quantitative genetic parameters of nitrogen use efficiency, twenty maize single-cross hybrids with varying nitrogen use efficiency were tested at two locations in the North China Plain. At both locations, the hybrids were grown under high (HN, 225 kg/hm^2 N) and low N levels. And no N fertilization on the LN field have lasted two years.

为研究玉米品种氮利用效率相关性状的遗传参数，本试验选择20个具不同氮利用效率的单交种在华北平原的2个地点同期进行试验，氮肥处理设高氮（施氮，折合纯氮225 kg/hm^2）和低氮（不施氮，其地块经过连续2年耕种使氮素耗竭）2个水平。

There was genetic differentiation among the populations and these differentiations were related with their environments.

结果表明，2种豚草种群内遗传变异丰富，每个形态性状均具有丰富的多态性，种群间存在着一定的遗传差异，且这些差异与其生态环境有一定的关系。

The density of tall fescue and kentucky bluegrass changes little during the whole evaluation period; while that of perennial ryegrass becomes very seldom during the summer.

在整个性状评定期间，高羊茅和草地早熟禾的密度变化较小，多年生黑麦草的密度变化很大；种内品种间密度差异很小。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
