Ina self-fertiizing species, maximum diversity can be captured by:
EXPLANATION
PGR Exploration, Conservation & International
- Population Genetics of Self-Fertilizing Species:
- In predominantly self-pollinated (autogamous) crops, natural self-fertilization minimizes intra-population heterozygosity and creates high genetic differentiation between isolated geographic landraces ($F_{ST}$ is very high).
- Most of the genetic diversity exists between different subpopulations rather than within a single subpopulation.
- Germplasm Sampling Strategy: To maximize allelic diversity, plant collectors must sample a greater number of diverse subpopulations/sites rather than collecting large numbers of individuals from a single population. (Correct answer: Option 1)
