abnormal regulation of transcription reversed parental genome-dependent asymmetric transcription midori reversed asymmetric transcription from parental genomes FYPO:0006675 2018-09-14T14:56:49Z reversed parental genome-dependent transcriptional asymmetry A transcription regulation phenotype observed during conjugation in which a pattern of transcriptional regulation that normally differs between parental genomes has the opposite parental specificity compared to normal. For example, a gene that is normally transcribed first from the P (h+) parental genome is instead transcribed from the M (h-) genome earlier.
