Options:
Answer:
Solution:
A species is a group of similar individuals that produces offspring that are fertile and capable of interbreeding. If a species population is reproductively isolated due to geographical barrier, this results in development of two separate species. Such species are called allopatric species. These species have exclusive areas of geographic distribution.
The evolution of a new species from an existing one due to reproductive isolation and present in the same geographical region is called sympatric species.
Organism groups that are closely related and have identical morphological features but reproductive isolation are termed sibling species. These groups even if they interbreed their offspring will be sterile. Two morphologically identical species that do not interbreed are referred to as sibling species; for exampleDrosophila pseudobsculaandD. persimilisare sibling species that do not interbreed.
Morphospecies is a means of classifying groups of organisms based on their morphological features.
