Summary of deletion alleles followed up in detail.

The table summarizes losses affecting OR loci for which we sought for homozygously deleted individuals using qPCR. Abbreviations: NR: not reported previously; DGV: intersecting variant previously reported in the Database of Genomic Variants (http://projects.tcag.ca/variation). ��Former status�� indicates as to whether this locus was reported as a ��deletion��, or ��CNV��, in previously published data sets. Boundaries of an event were here taken from the respective (confirmatory) data source (except for the novel deletions III and VIII). *For deletion III, 4 heterozygotes (and no homozygous deletion) were identified by combinations of allele-specific qPCR reactions.**For all deletions, except deletion III, allele frequencies were estimated as square root of proportion of homozygously deleted individuals. Frequency of deletion III allele was estimated as the number of deletion alleles (n = 4) out of total number of chromosomes tested (n = 46).
