Which reproductive barrier is most likely to prevent interbreeding between a its diploid sister species? O Behavioral isolation: the two species will not recognize each other as mates Gametic isolation: sperm and egg with different chromosome numbers cannot comp Hybrid infertility: differences in chromosome numbers will result in infertile hybrids O Mechanical isolation: differences in reproductive structures will prevent interbreedin
