Number of crosses showing amplification of maternal and paternal haplotypes.*

*��mat�� tested positive for maternal mtDNA only; ��both�� tested positive for both maternal and paternal mtDNA; ��U�� paternal inheritance cannot be determined because the paternal genome is identical to the maternal; ��-�� no eggs or nymphs were collected for this cross at this time period or samples that were collected failed to extract/amplify (only one pooled sample of 6-week old eggs failed to extract�Ca -decula M��-decim F; only two extractions failed to amplify and both of these were -decim M��-decim F 16-month old nymphs). Fewer offspring from crosses involving -decim males and heterospecific females were sampled because -decula and -cassini females most often rejected -decim males.
