Abstract
The genetic composition and diversity of chicken breeds/populations have been shaped through selective breeding and management practices. Understanding the genetic diversity of chicken breeds can inform breeding strategies and conservation priorities as well as improve desirable traits in offspring. Assessing genetic diversity between indigenous and exotic breeds provides insights into the benefits of selective breeding and/or crossbreeding. Various studies have investigated genetic diversity indicators in indigenous chicken breeds. Markers are central to study diversity, among them DNA-based markers have proven to be more effective than protein-based markers due to their polymorphism, codominance, and ease of genotyping. Among the 19 diverse chicken breeds currently registered in India, the indigenous Aseel and Kadaknath breeds have more peculiar distinctive characteristics. Synthetic chicken breeds developed by various research organizations exhibit variations in physical features and closely resemble native breeds in terms of eggshell color and meat quality. Overall, chicken is a significant species, because of its economic importance, short reproductive cycle and high fertility. This review shall deal with various aspects of genetic diversity explored in chicken breeds in Indian context.
期刊介绍：
Ecological Genetics and Genomics publishes ecological studies of broad interest that provide significant insight into ecological interactions or/ and species diversification. New data in these areas are published as research papers, or methods and resource reports that provide novel information on technologies or tools that will be of interest to a broad readership. Complete data sets are shared where appropriate. The journal also provides Reviews, and Perspectives articles, which present commentary on the latest advances published both here and elsewhere, placing such progress in its broader biological context. Topics include: -metagenomics -population genetics/genomics -evolutionary ecology -conservation and molecular adaptation -speciation genetics -environmental and marine genomics -ecological simulation -genomic divergence of organisms
