Low-coverage resequencing detects meiotic recombination pattern and features in tomato RILs.

Traditional plant breeding relies on meiotic recombination for mixing of parental alleles to create novel allele combinations. Detailed analysis of recombination patterns in model organisms shows that recombination is tightly regulated within the genome, but frequencies vary extensively along chromosomes. Despite being a model organism for fruit developmental studies, high-resolution recombination patterns are lacking in tomato.
