Question

question 29 1 pts which of the following must take place for speciation to occur? polyploidy geographic isolation hybridization reproductive isolation

Explanation:

Speciation is the formation of new and distinct species in the course of evolution. Reproductive isolation is essential as it prevents gene - flow between populations, allowing them to diverge genetically and form new species. Polyploidy can cause speciation but is not a necessary condition. Geographic isolation can lead to speciation but is not always required. Hybridization usually reduces genetic differences rather than causing speciation.

Answer:

reproductive isolation
