Based on the information above, which of the following statements is true? 37 chapters | Birds Reproductive isolation is a collection of mechanisms, behaviors, and physiological processes that prevent the members of two different species that cross or mate from producing offspring, or which ensure that any offspring that may be produced is not fertile. Gametes of different species may fail to attract one another. To accomplish this, gametes carrying genes fuse to create zygotes which then grow and differentiate. The synchronous spawning of many species of coral in marine reefs means that inter-species hybridization can take place as the gametes of hundreds of individuals of tens of species are liberated into the same water at the same time. But interspecies offspring like ligers (tiger + lion), zebroids (zebra + horse), grolar (polar bear + grizzly), and wholphins (whale + dolphin) are not the norm in the world of organisms. c. an area's climate interferes with speciation.
