查询词典 polymorphic

The genetic variations and polymorphisms of six microsatellite loci were analyzed to determine the population structure and breeding progress of BMY and Brahman cattle. The range of polymorphic information content of six loci was 0.524～0.752. The unbiased expected and observed heterozygosity were similar and were 0.7376 and 0.7396,0.6412 and 0.6537 for BMY and Brahman cattle, respectively. The expected heterozygosity was relatively high in the second generation of BMY in inter se breeding, which was congruent with the breeding progress.

对6个牛微卫星座位的遗传变异及多态性分析，以期了解BMY牛和婆罗门牛的群体遗传结构与育成情况。6个微卫星座位的多态信息含量为在0.524～0.752间，BMY牛、婆罗门牛两个群体的平均期望杂合度和观察杂合度值接近，分别为0.737 6和0.739 6，0.641 2和0.653 7，进入横交固定第二世代的BMY牛期望杂合度值较高，这与我们的育种进展相符。

The result was not consistent with what was predicted by Chitty's polymorphic behavior hypothesis; aggressive behaviors of dyadic encounters were not correlated to body mass but to the difference of body mass negatively which means that there were more aggressive behaviors between dyadic encounters with similar body mass.

As they are evenly dispersed throughout genomes, usually characterized as codominant and highly polymorphic systems amenable to genotyping by polymerase chain reaction, and generally inherited in a Mendelian fashion, microsatellites have become instrumental as genetic markers in many areas.
