A groundbreaking study published in the Scientific Research Journal of Biology and Life Science has shed new light on the genetic mechanisms responsible for the vibrant colors seen in fish and crustaceans. The research, conducted by Murwanashyaka Michel of Kibogora Polytechnic University and Lihua Jiang of Zhejiang Ocean University, explores how gene and genome duplications drive the evolution of pigment synthesis pathways in these aquatic organisms.
