Definition of introgressive in English:




See introgression

‘Plant biologists have long been comfortable with the notion that ‘good species’ can still exchange some genes via introgressive hybridization as have biologists concerned with hybrid zones.’
  • ‘Incongruence among data sets can arise from various biological processes, including introgressive hybridization, recombination, and gene conversion.’
  • ‘For instance, introgressive events, even when rare, may be more important than mutations as a source of novel genetic variability within taxa.’
  • ‘It is possible that the inland plants Hodgdon called variety typica represent introgressive hybrids between L. pulchella and L. intermedia.’
  • ‘Because hybrids are usually fertile, they can often produce introgressive hybrids with the parental species or triple hybrids with another taxa.’
