polygenesis

Heredity modes of 6 traits were studied by analysis of population genetics , by the method of family combination analysis , by the methods of proband ' s sib analysis , segregation analysis , the threshold model of polygenes , and analysis of typical family trees , according to the data of the 72 families . the relative importance between genetic and environmental effect on each character was evaluated by comparing the coherence of twins . gene frequencies of 5 genetic characters , calculated from han group in huhhot , were compared with other groups by u - test so as to study the population or nationality difference in heredity 采用群體遺傳學分析、家系組合分析法、先證者同胞法、分離分析法及多基因閾值模式分析方法對所得家系資料進行了統計學分析,結合家系系譜分析探討了上述6項特征的遺傳方式;通過雙生子一致率的比較,對上述特征的遺傳與環境效應的相對重要性進行了評價;計算了呼和浩特市漢族群體5對遺傳性狀的基因頻率,采用u檢驗方法與相關文獻報道的其他群體進行了比較,探討了不同種族間或民族間的遺傳差異性。

Through similar and supplementary action, polygenes can have important effects on total variability . 通過相同的和添加的作用,多基因可以對總的變異起重大的影響。
