Abstract

Background: 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.

Materials and methods: Crow (1958) and the modified method by Johnston and Kensinger (1971) were used for the present purpose.

Results and discussion: 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.

印度卡纳塔克邦Kodagahalli村高达人自然选择的机会指数。

背景:为了了解选择是如何在Gowda种群中运作的，计算了选择机会指数，并将本研究结果与其他南印度(SI)种群的一些相关结果进行了比较。材料和方法:本研究采用Crow(1958)和Johnston和Kensinger(1971)改进的方法。结果和讨论:考虑到许多印度人口的范围，总选择强度指数(I)被发现是中等的。考虑到生育和死亡率的遗传差异，自然选择似乎在塑造高达种群的遗传构成中起着重要作用。对数据的分析表明，由于生育而产生的指数似乎比死亡率对选择的贡献更大。这一趋势可能是由于高达族的生活条件和卫生保健系统较好，这对高达族种群通过自然选择的进化机制降低死亡率的贡献有积极影响。
