In swordtails, gene copy number variation is associated with alternative male mating strategies, size and puberty. Though it is unclear how the different aspects are linked mechanistically, the nature of the gene, a melanocortin receptor, suggests avenues for future inquiry.
在剑尾鱼中，基因拷贝数变异与雄性的替代交配策略、体型和青春期有关。尽管不同方面在机制上的联系尚不清楚，但该基因（一种黑皮质素受体）的性质为未来的研究提供了线索。
