Q.28
Which of the following is a strategy used to maintain genetic diversity in captive populations?
- Conservation of Genetic Diversity in Captivity:
- Captive breeding and hatchery populations are prone to rapid loss of genetic diversity via genetic drift and inbreeding depression.
- Controlled Mating (Pedigree-Based Breeding / Circular Mating): A systematic breeding management strategy designed to equalize family contributions, minimize mean kinship, and prevent mating between close relatives, thereby preserving long-term heterozygosity and allelic richness.
- Correct Option: Option 4 (Controlled mating).
