Inbreeding coefficients and effective migrants for the immigrant Punjabi Khattri and Arora of Delhi were estimated from isonymous marriages by five methods: sigma qm2, sigma qf2, sigma qm qf, sigma qm2+f and sigma Ie (pair). It was found that the method sigma qmqf gives better estimates as expected by the isonymy method -- sigma Ie (Pair). A higher estimate of the random inbreeding coefficient suggests that Arora is more inbred than Khattri. The lesser number of effective migrants observed for Aroras also points to their relatively isolated nature. The two groups however, behave as one broad endogamous-panmictic unit.
通过sigma qm2、sigma qf2、sigma qm qf、sigma qm2+f和sigma Ie（配对）这五种方法，根据同名婚姻对德里移民旁遮普卡特里人和阿罗拉人的近亲繁殖系数和有效移民数量进行了估计。结果发现，正如同名法——sigma Ie（配对）所预期的那样，sigma qmqf方法给出了更好的估计值。对随机近亲繁殖系数的较高估计表明，阿罗拉人的近亲繁殖程度高于卡特里人。观察到的阿罗拉人的有效移民数量较少，这也表明他们相对孤立。然而，这两个群体表现为一个广泛的内婚制-随机交配单位。
