  1. Seven SNPs were used to fine map hotspot Cdkn1c. The center of the hotspot was mapped to between SNP3 and SNP5. The central SNP (SNP4) is converted to the non-initiating strand during meiotic recombination. A slight statistical bias is found for DSB initiation on the paternal chromosome (P = 0.13). SNP positions are indicated in parentheses (base pairs – Build 36).
