The fractional complex transform is proposed to convert a partial fractional differential equation with Jumarie's modified Riemann-Liouville derivative into its ordinary differential equation. It is shown that the considered transform and method are very efficient and powerful in solving wide classes of nonlinear fractional order equations.展开更多
目的:了解浙江畲族群体4个X染色体短串联重复序列(short tandem repeat,X-STR)基因座DXS7132、DXS6804、DXS6799、DXS9898的等位基因及基因型频率分布。方法:从无血缘关系的260名浙江畲族个体的抗凝血中提取DNA,进行PCR扩增,聚丙烯酰胺...目的:了解浙江畲族群体4个X染色体短串联重复序列(short tandem repeat,X-STR)基因座DXS7132、DXS6804、DXS6799、DXS9898的等位基因及基因型频率分布。方法:从无血缘关系的260名浙江畲族个体的抗凝血中提取DNA,进行PCR扩增,聚丙烯酰胺凝胶垂直电泳(PAGE)并银染。结果:4个基因座检出6、6、6、7个等位基因,4个基因座基因型频率分布(女性个体)均符合Hardy-Weignberg平衡(P>0.05);观测杂合度大于0.4759,多态信息含量均大于0.4663,女性个体识别力均大于0.7096,男性个体识别力均大于0.4147。结论:4个基因座均具有较高的遗传多态性,是较理想的遗传标记系统,为浙江畲族人群法医个体识别、亲子鉴定及遗传学研究提供依据。展开更多
