Step by Step Solution
There are 3 Steps involved in it
Step: 1
The detailed answer for the above question is provided below 1 Adaptation to Changing Environments Genetic diversity provides the basis for adaptation to environmental changes allowing fish populations to evolve traits suited to diverse habitats and ecological conditions Variation in alleles ensures that some individuals possess advantageous traits such as temperature tolerance salinity tolerance and disease resistance enabling populations to thrive in fluctuating environments and face emerging challenges including climate change pollution and habitat degradation Ecosystem Resilience and Stability High genetic diversity contributes to the resilience and stability of aquatic ecosystems by enhancing the adaptive capacity of fish populations to environmental perturbations Diverse gene pools reduce the risk of genetic bottlenecks and inbreeding depression which can weaken population ...
