To estimate the genetic diversity of germplasm collection, a technique involving multivariate analysis based on ordination giving graphical representation is:
Show Hint
- PCA: Ordination, graphical representation.
- D^2 analysis: Genetic divergence.
- Cluster analysis: Grouping of individuals.
- D^2 analysis
- Principal Component Analysis
- Cluster analysis
- Linkage analysis
The Correct Option is B
Solution and Explanation
This question tests knowledge of multivariate analysis techniques used in genetics.
Step 2: Detailed Explanation:
Principal Component Analysis (PCA) (B) is a technique involving multivariate analysis based on ordination.
It provides a graphical representation of genetic diversity.
PCA reduces the dimensionality of data while retaining most of the variation.
Other techniques:
- D^2 analysis (A): Mahalanobis distance analysis (quantifies genetic divergence).
- Cluster analysis (C): Groups individuals into clusters based on similarity.
- Linkage analysis (D): Used for mapping genes.
Thus, PCA is the technique that gives a graphical representation.
Step 3: Final Answer:
Thus, Principal Component Analysis is used for graphical representation of genetic diversity, which corresponds to option (B).
