'apparent': a simple and flexible R package for accurate SNP-based parentage analysis in the absence of guiding information.

ABSTRACT:

Background

The accurate determination of parent-progeny relationships within both in situ natural populations and ex situ genetic resource collections can greatly enhance plant breeding/domestication efforts and support plant genetic resource conservation strategies. Although a range of parentage analysis tools are available, none are designed to infer such relationships using genome-wide single nucleotide polymorphism (SNP) data in the complete absence of guiding information, such as generational groups, partial pedigrees, or genders. The R package ('apparent') developed and presented here addresses this gap.

Results

'apparent' adopts a novel strategy of parentage analysis based on a test of genetic identity between a theoretically expected progeny (EP_ij), whose
