Transcriptional quiescence of paternal mtDNA.
Embryos from parental species and reciprocal hybrids were analyzed by RT-PCR at representative stages indicated. β-actin was used as a loading control. (a) cytb expression in the embryos of goldfish (G) and blunt-snout bream (B). (b) Lack of gene expression from paternal mtDNA of blunt-snout bream (asterisks) and goldfish (hashes). Shown here are cytb, nd6, atp6 and 16s rRNA genes. For abbreviations see legend to Fig. 1.
