In order to understand how selection is operating in the Gowda population, the index of opportunity for selection was calculated and the present findings were compared with some related findings from other South Indian (SI) populations.
Crow (1958) and the modified method by Johnston and Kensinger (1971) were used for the present purpose.
The index of total selection intensity (I) was found to be moderate taking into consideration the range for many Indian populations. Considering certain differences in fertility and mortality heritable, it appears that natural selection play an important role in shaping the genetic constitution of the Gowda population. Analysis of data indicates that the index due to fertility seems to contribute more towards selection than mortality. This trend might be because of better living condition and health-care system among the Gowdas which have a positive impact on the lower contribution of mortality for the evolution mechanism of the Gowda population through natural selection.
为了解选择作用在 Gowda 人群中的情况，计算了选择机会指数，并将当前研究结果与其他南印度（SI）人群的一些相关研究结果进行了比较。
本研究采用了 Crow（1958 年）以及 Johnston 和 Kensinger（1971 年）修改后的方法。
考虑到许多印度人群的范围，发现总选择强度指数（I）处于中等水平。鉴于生育力和死亡率存在一定的可遗传差异，自然选择似乎在塑造 Gowda 人群的基因构成方面发挥着重要作用。数据分析表明，生育力导致的指数对选择的贡献似乎比死亡率更大。这种趋势可能是由于 Gowda 人群中较好的生活条件和医疗保健系统，这对通过自然选择的 Gowda 人群进化机制中死亡率的较低贡献产生了积极影响。
