Fish genetics is the study of the genetic makeup and inheritance patterns of fish species. This field of research explores how genes are passed down from generation to generation, and how they influence the physical characteristics, behavior, and overall health of fish populations. By studying fish genetics, researchers can better understand the evolutionary relationships between different fish species, identify genetic variations that may make some fish more resilient to environmental challenges, and improve breeding programs to enhance desirable traits in aquaculture. Fish genetics research also plays a crucial role in conservation efforts, helping to identify genetically distinct populations and develop strategies for maintaining genetic diversity within wild fish populations.
