Question

question 15 of 19
what is reproductive isolation?
○ prevention of gene flow between two populations due to physical or behavioral barriers
○ evolution of analogous structures not present in the last common ancestor of two species
○ two species that are capable of producing viable hybrids through interbreeding
○ the divergence of two species from a common ancestor while in the same geographical location
○ two species diverging from a common ancestor due to geographical isolation

Explanation:

Reproductive isolation refers to mechanisms (physical like geographic separation, behavioral like mating rituals) that stop gene exchange between populations, a key concept in speciation. The other options describe convergent evolution (analogous structures), hybridization capability, sympatric speciation, and allopatric speciation respectively, not reproductive isolation itself.

Answer:

prevention of gene flow between two populations due to physical or behavioral barriers
