Two morphologically similar populations are intersterile. They belong toa)One speciesb)Two biospeciesc)Two sibling speciesd)None of the aboveCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Two morphologically similar population are intersterile. They belong to one genus i.e two sibling species. Which species are assigned to a genus is somewhat arbitrary. Although all species within a genus are supposed to be "similar" there are no objective criteria for grouping species into genera. If the offspring of two species is fertile then the animals are of the same species, if the offspring is sterile they are of different species.

Answer

Option C

Answer

As name intersterile says,  the incapability of producing offsprings by interbreeding, ' species 'with morphological differences can undergo reproduction n produces offsprings by interbreeding( not the populations n species with morphological difference can undergo this).

Answer

Explanation:
Intersterility is a key concept in the field of speciation, which refers to the inability of two populations to produce viable, fertile offspring when they are crossed.

Two sibling species:
When two morphologically similar populations are intersterile, it indicates that they are likely to be sibling species. Sibling species are closely related species that have recently diverged from a common ancestor. Despite their morphological similarities, they have evolved reproductive barriers that prevent them from interbreeding successfully.

Significance of intersterility:
Intersterility is a crucial factor in defining species boundaries and understanding the process of speciation. It helps to maintain the genetic integrity of different species by preventing the exchange of genes between them. This plays a vital role in promoting biodiversity and the evolution of new species over time.
In conclusion, when two morphologically similar populations are intersterile, it suggests that they are likely to be sibling species that have evolved reproductive barriers to maintain their genetic distinctiveness. This phenomenon highlights the intricate mechanisms involved in speciation and the diversity of life on Earth.
