Note.—Biparental inheritance was determined as the compatibility ratio of single heteroplasmic positions (SHPs) between each hybrid and the putative paternal parent. SHPs were searched in the 1,564 nonredundant positions corresponding to the SNV set. A certain position was defined as SHP when the minor allele was present in at least 5 out of a minimum of 1,000 reads. The analyses were performed against the whole collection of sequenced accessions although the table shows the top five hits for putative paternal parents containing more than 70 heteroplasmic compatible positions. Numbers between parentheses after the citrus groups indicate number of species involved in the estimation of the values.
