A- and B/S-genome Ancestry in Ae. tauschii as Reflected and Quantified by the Number of A- and B/S-genome Diagnostic SNPs/Indels for Nuclear Genes Encoding CECs, and Compared with All Nuclear Genes as a Control for Systematic Biases.

Genome-diagnostic SNPs/indels	Number of SNPs/Indels
	Nuclear Genes Encoding CECs	Whole-genomic Genesb
A-genome SNPs/indels	17,502c,d	1,547,018c,d
B/S-genome SNPs/indels	16,541c,d	1,519,036c,d
Ambiguous SNPs/indels with undetermined genomic origina	36,070c	6,922,851c

^aAmbiguous SNPs/indels could result from autapomorphic evolution of SNPs/indels following speciation and/or hybridization, or from segregating ancestral polymorphism, or from multiple mutations at a site that obscures history.

^bBackground whole-genomic genes includes the putative predicted nuclear CEC genes.

^cDenotes numbers utilized in Fisher’s Exact test, with the numbers of SNPs/indels identified in nuclear genes encoding CECs and background whole-genomic genes as observed and expected counts, respectively.

^dDenotes respective numbers utilized in Binomial test, with the null hypothesis being that the probability of having A-genome SNPs/indels is equal to that of having B/S-genome SNPs/indels in nuclear genes encoding CECs. The expected success rate is estimated as 0.505, which was calculated as 1,547,018/(1,547,018 + 1,519,036).
