WebJul 21, 2005 · Self-incompatibility (SI) and seed dormancy complicate breeding in elite × wild hybrids (Seiler 1992 ), and the genetic mechanisms underlying SI, self-pollination (SP), and seed dormancy in sunflower are either unknown or superficially known. WebJul 23, 2024 · We examine here the detailed mechanistic basis of hybrid incompatibilities between two allopatric lineages, for a genotype-phenotype map of developmental system drift under stabilising selection, where an organismal phenotype is conserved, but the underlying molecular phenotypes and genotype can drift.
