The assumption of infinite population size is a useful idealization, but most real populations are finite. This chapter tackles the consequences of "random genetic drift"—the random fluctuations in gene frequencies due to the sampling of gametes each generation. This is where the concept of effective population size ( Ne ) is formally defined and explored in depth, showing how it determines the rate of inbreeding, the loss of genetic variation, and the variance in gene frequency among populations.
These journals often publish articles on population genetics theory, applications, and empirical studies. You can search for articles and papers on these topics using online academic databases such as PubMed, Google Scholar, or JSTOR.
The main goal is to understand how forces such as selection and drift interact to create the complex patterns of variation observed in nature. 2. The Hardy-Weinberg Principle: A Baseline Model an introduction to population genetics theory pdf

The transfer of alleles into or out of a population due to the movement of individuals. 4. Key Concepts in Population Genetics Theory Genetic Variation and Structure
You might ask: Given modern genomics (GWAS, CRISPR, whole-genome sequencing), do I really need a 1970s math book? These journals often publish articles on population genetics
Individuals pair up without regard to their genotypes.
Published in 1970 by James F. Crow and Motoo Kimura, this book is not a casual read. It is a to the stuff of life: the slow, grinding change of allele frequencies.
