tailieunhanh - PHYTOCHEMICALS – A GLOBAL PERSPECTIVE OF THEIR ROLE IN NUTRITION AND HEALTH

The theoretical metrics developed, such as genetic variance and heritability (Fisher, 1930; Wright, 1931), provided the quantitative standards necessary for the evolutionary synthesis. Further research has focused on the origin of genetic diversity, its maintenance and its role in evolution. Simple questions such as “who breeds with whom” initiated studies on the relatedness of populations. These investigations led to the formation of metapopulation theory, where a group of spatially separated populations of the same species interact at some level and form a coherent larger group (Hanski, 1998). The discovery of spatial structure in populations was a key element in the early concepts and models of population ecology, genetics. | PHYTOCHEMICALS - A GLOBAL PERSPECTIVE OF THEIR ROLE IN NUTRITION AND HEALTH Edited by Venketeshwer Rao Phytochemicals - A Global Perspective of Their Role in Nutrition and Health Edited by Venketeshwer Rao Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
