HABITAT TYPE AND CLIMATIC ZONE CORRELATE WITH GENOME SIZE VARIATION IN OSTEICHTHYES FISHES
Journal Title: International Journal of Zoology and Research (IJZR) - Year 2017, Vol 7, Issue 1
Abstract
Cytogenetic and environmental factors have been reported to cause variations in the genome size within the species. However, the broad scale genome size variation of a class of vertebrate especially Osteichthyes fishes across the different climatic zone and habitat conditions hasyet to be documented. In this study, we analyzed the genome size variation of 285 species of Osteichthyes fishes distributed across the marine and freshwater habitat. We found that habitat and climatic zone showed a significant pattern of genome size variation, however, the body size, chromosome number and diversity rate has no strong correlation with the genome size.
