Which of the following is known as adaptation of traits to better fill a niche?

Explanation

The correct answer is Specialization. Specialization refers to how organisms adapt particular traits to perform specific functions or to thrive in certain environmental conditions, thereby filling a specific ecological niche. This process helps organisms become more efficient in their roles within their ecosystems.Polymorphism is incorrect because it involves the existence of multiple forms within a species, not necessarily linked to niche adaptation.Gene linkage is incorrect as it pertains to genes being inherited together, which is unrelated to niche adaptation.Replication is incorrect because it relates to the process of copying genetic material and does not involve adaptation to environmental niches.
