Speciation genes are the specific sets of genes that are responsible for the process of speciation or the emergence of new species. These genes are responsible for creating reproductive barriers between organisms of different populations that lead to their divergence. Some synonyms for speciation genes include isolation genes, diversification genes, and genetic differentiation genes. These genes can also be referred to as reproductive isolation genes, which are the genes responsible for creating and reinforcing reproductive barriers between species. Other synonyms include hybridization genes, which are the genes that control the process of creating hybrids between different species. Overall, speciation genes are the key players in the evolution of new species and are crucial for maintaining biodiversity on our planet.
