Number of Genes Containing Parent-of-Origin SNPs

SNP Patterns in Reciprocal Crosses	Male Progeny	Female Progeny	Total
Genes with paternal monoallelic SNPs	0	0	0
Genes with paternal biased SNPs	7	4	11
Genes with maternal monoallelic SNPs	1 (+1 mitochondrial)	0 (+1 mitochondrial)	1
Genes with maternal biased SNPs	7	3	10
Total monoallelic	1	0	1
Total biased	14	7	21
Total genes with parent-of-origin expressed SNPs	15	7	22

Note.—Genes with parent-of-origin SNPs are categorized 1) according to their expression in male and female progenies and 2) according to their expression pattern (i.e., maternal or paternal, and monoallelic or biased).
