The situation resembles a stalemate in which the genes essentially do not change. Duplication resolves this conflict by allowing each duplicated gene to perform a singular function. The overall function of the genes in a given pathway is preserved, and now mutations in the genes can be selected for that will optimize that specific function.
All genes with sufficient sequence similarity to have evolved from a common ancestor anywhere in evolutionary time are ________, while ________ are genes in different species that arose from the same gene in a very recent ancestor of the two species and ________ arise by duplication events within the same species.
