| 摘 要： | 对抽样调查的身高数据进行计量分析,建立了子代对亲代身高的回归分析模型,揭示了子代身高与亲代身高的遗传率;研究结果表明,父母身高对下一代的遗传率强度不同,母亲要强于父亲;子女接受遗传的效应也不一样,女儿要强于儿子;建立了性别遗传模型,深入研究了亲代父母之间的身高差对子代性别的影响,亲代身高差越大,则生女孩的几率就越大,反之生男孩的几率就越大．

| Abstract: | A regress analytic model,which releases the rate of heredity probability from parents to their descendants,is built by quantity analyze on the spot check height data.It shows that father's heredity rate differs from mother's heredity rate,and the latter is bigger than the former.Heredity effect received by son and daughter is different and daughter receives more than son.Moreover,a sex heredity model is built.It further studies the influence of the height differ- ence between parents on the children.The result shows that the higher is the father than mother, the bigger is the probability of the birth of daughter,whereas the bigger is the probability of son. |
