The estimates of opportunity for natural selection are reported for four endogamuus Andhra castes, namely. Chakali (0.6274). Kummari (0.9572). Mangali (0.6792) and Madiga (0.6957) The contribution of fertility to the total index is greater than the contribution of mortality among four ...
What are the main factors for evolution? What are the four forces of evolution? What conditions can cause evolution to take place? What are the four evolutionary forces? What have been the three major changes in human evolution? What are the four principles of natural selection?
In goat breeds, the domestication followed by artificial selection for economically important traits have shaped genetic variation within populations, leading to the fixation of specific alleles for specific traits. This led to the formation and evolutio

These differences may be associated with geographical, cultural, economic, and demographic factors. In Sub-Saharan Africa, rapid population growth, inefficient agriculture and industry, and inadequate health infrastructure lead to malnutrition and disease [26]. Inadequate food supply, low household income...

Scheubel (1973) proposed that these are intraspecific differences resulting from environmental factors, especially food supply and temperature. The Weishan population fits well with the following characters of E. lwoffi: (i) the inverted bell-shaped zooids; (ii) single-layered peristomial lip; (...

(SCZ patients have poor cognitive performance compared to normal individuals, including poor working memory and executive function)3. So far, the pathogenesis of SCZ remains largely unknown. Nevertheless, high heritability indicates the pivotal role of genetic factors in SCZ. To uncover the risk ...
