Question

Answer

Hybridization is not applicable to the bilogical species concept

Answer

Answer is option A i.e. 'Hybridisation'
The biological species concept defines a species as members of populations that interbreed in nature. According to this concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Reproductive isolation, natural selection and gene pool are applicable to one species.
Hybridisation, on contrary, occurs due to process of combining two different species of organisms to create a hybrid.
Hence, 'hybridisation' is not applicable to biological species concept.

Answer

Introduction:
The Biological Species Concept (BSC) is a concept used by biologists to define and distinguish species based on their ability to interbreed and produce fertile offspring. It is one of the most widely accepted species concepts in the field of biology.

Explanation:
The Biological Species Concept (BSC) focuses on the reproductive compatibility and isolation of populations. Here's a detailed explanation of why option 'A' (Hybridization) is not applicable to the BSC:

1. Hybridization: Hybridization refers to the interbreeding between different species or closely related species, resulting in the formation of hybrids. While hybridization does occur in nature, it is not applicable to the BSC because the concept relies on reproductive isolation and the inability to produce fertile offspring between different species.

2. Natural Population: The concept of a 'natural population' is applicable to the BSC. A natural population refers to a group of individuals of the same species that inhabit a specific geographical area and have the potential to interbreed.

3. Reproductive Isolation: Reproductive isolation is a fundamental aspect of the BSC. It refers to the barriers that prevent or reduce gene flow between different populations, leading to the divergence of species. Reproductive isolation can be achieved through various mechanisms such as geographic barriers, behavioral differences, or genetic incompatibilities.

4. Gene Pool: The gene pool is the total collection of genes and alleles present in a population. It includes all the genetic variations that can be passed on to the next generation. The gene pool is relevant to the BSC because it influences the genetic diversity within a species and can play a role in reproductive isolation.

Conclusion:
In conclusion, the Biological Species Concept (BSC) is based on reproductive isolation and the inability to produce fertile offspring between different species. While hybridization does occur in nature, it does not align with the BSC because it involves interbreeding between different species or closely related species, which goes against the criteria of reproductive isolation. Therefore, option 'A' (Hybridization) is not applicable to the Biological Species Concept.
