• Pedigree Reconstruction in Aquaculture:
• In mass-spawning or mixed communal rearing of fish families, physical tagging of fry is impossible due to their small size.
• Microsatellite and SNP marker genotypes are used to infer parentage based on the Probability of Exclusion ($PE$):
• An individual candidate parent (or parental pair) is excluded if it does not share alleles that the offspring must have inherited according to Mendelian transmission.
• All non-compatible parents are systematically eliminated until a unique, compatible parental pair remains.
• nalysis:
• (Probability of exclusion): Correct.

Correct option: (1) Probability of exclusion
