- Which process in a hybrid zone increases the likelihood of speciation? A. stability – when a hybrid zone remains the same B. reinforcement – when a hybrid zone widens and fewer hybrids are formed C. convergence – when a hybrid zone narrows and more hybrids are formed D. fusion – when a hybrid zone disappears and separate species fuse into oneGive typing answer with explanation and conclusion Explain why speciation is very different in sexual and asexual organisms. Explain how these differences relate to different definitions of “species.” Make sure to comment on which definitions of “species” are more appropriate for a given set of circumstances.Write a short essay describing the roles ofmutation, migration, and selection in bringing about speciation.
