Abstract
This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker
density, error threshold selection, and different SNP selection strategies on parentage assignment
accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation
between the quantity of SNP markers and the accuracy of parentage assignments, consistent with
existing literature. We discovered that error threshold selection significantly influenced assignment
accuracy and recommended its careful consideration based on population genetic characteristics.
Furthermore, our interval-based SNP selection analysis showed that SNP density crucially impacts
parentage assignment accuracy. Notably, random SNP selection across the genome yielded more
accurate assignments than chromosome-specific selection, emphasizing the importance of diverse
and representative SNP sets. These findings provide valuable guidance for future genetic research
in parentage assignment.
