查询词典 inbreeding

Although none of Darwin's children had obvious documented physical or mental deformities, the three who died appear to have suffered from infectious disease, which is more likely to be contracted in those with higher levels of inbreeding, Berra and his colleagues noted.

Berra和他的同事们提出，虽然达尔文的孩子中没有任何明显记录在案的身体或心理上的畸形，那三个死去的孩子却是由于传染性疾病死亡的，而高度近亲繁殖的后代更容易染上这样的病。

BecauseIMLC is involved in not only Bulmer′s effect of selection on variance decrease but alsoancestor and its offspring′s "selective advantage"by the regression of offspring′s breedingvalues on their ancestor′s,it comes to the conclusion that IMLC could predict morereasonable and more accurate rates of inbreeding in a small closed nucleus.

作者认为长期贡献方法预测闭锁核心选择群体的近交率结果比Robertson方法更合理且更准确，这是因为长期贡献方法不但考虑了闭锁群体因选择而遗传方差降低的Bulmer效应，而且，通过后裔指数育种值对其祖先指数育种值的回归考虑了被选个体本身及其后裔的选择优势。

The results based in microsatellite polymorphisms showed that the average heterozygosity in Huiyang Bearded and Xinghua chickens which were sampled from conserver populations, and Yuehuang which has been inbreeding for more than 10 years was low, buti n Qingyuan Partridge chicken which was sampled from Qingyuan city, Guangdong, was high.

用5个座位的微卫星标记和70个10碱基引物得出的RAPD，研究分析了惠阳胡须鸡、杏花鸡和清远麻鸡3个广东地方鸡种和培育品种粤黄鸡的群体遗传变异及相互间的关系，并讨论了微卫星多态性和RAPD这两种标记在应用于群体遗传变异及亲缘关系等方面分析的意义。

In addition, the earlier embryogenesis processes of crossbreeding and inbreeding were observed directly by common microscope.

两个交配组合的早期胚胎发育形态基本一致，时间上存在一定的差异。

Endodeme is a deme composed of predominantly closely inbreeding but dioecious individuals.

同系同群种是由近亲繁育占优势，但雌雄异株的个体组成的同群种。

It was concluded that the stemma equimultiple random select cross method could constrain the increments of inbreeding coefficient.

采用家系等量随机选配法保存鸡种，可有效地控制保种群近交系数的增长。

The "stemma equimultiple random select cross method" and "random mating method" were used to propagate offspring population of Langshan chicken. For each population, the pedigree of individuals were ascended up to 5 generations. Then, their generation increment of inbreeding coefficient was caculated using the regression slope rate.

以狼山鸡为素材，利用"家系等量随机选配法"和"随机交配法"2种保种方法进行继代繁殖鸡群，每个保种群每个世代的鸡只均逐只编制往上追溯5代的系谱图，利用回归斜率分析方法计算世代增量。

Unfortunately, some of these colors require extensive inbreeding to obtain; double dapples are often born eyeless or with severely underdeveloped eyes.

不幸的是，一些色样是需要广泛的近亲繁殖来获得的；双色花斑的犬就经常出生就失明，或眼部严重发育不足。

These results suggest that:(1) kin recognition is primary mechanism of inbreeding avoidance in estrus female root voles;(2) memory of a siblings scent may be a mechanism of sibling recognition by estrus females, and familiarity after weaning can reinforce permanence of this memory;(3) post coital familiarity may be a mechanism of maintaining inbreeding avoidance in female root voles.

故认为：断奶后嗅觉识别持久力是发情雌性根田鼠亲属识别的机制，亲属识别是最初发情的雌性根田鼠配偶选择中近交回避的首要途径和机制，熟悉性是维持雌性根田鼠配偶选择实现近交回避的机制和特征。
