1. The genetic diversity and their sibship among Chinese early-fruiting walnut cultivars were investigated and their fingerprintings were established in the research.

2. Sibship between 29 sugarcane cultivars and 12 ancestor species was analysed with RAPD .

3. The research is to clarify the sibship and geographic distribution of Artemisia frigida Populations.

4. Obtains the cluster chart had basically reflected these Frritillaira"s sibship , indicated from this, the RAPD method may be able to appraise Frritillaira"s quality specification.

5. A significant positive association was present in higher-socioeconomic-status (SES) participants only. Results were very similar for the related variable of sibship size.

6. Educational stratification theorists have long been interested in the effects of sibship configurations on educational achievement.
