Example of genetic isolation
Many species fall somewhere between generalist and specialist on the generalist specialist range. Such species generally exhibit moderate environmental specialization, being neither pure generalists nor pure specialists, resulting in fluid changes that must be subjective when categorizing species. Despite their considerable habitat specialization, environmentally transitional species generally do not exhibit the low genetic diversity seen in pure specialists, but instead, e… WebMar 11, 2024 · Examples of gametic isolation occur in many ocean invertebrates where they release their gametes directly into the surrounding water, hoping that random fertilization from other members of the...
