saltensis occur in sympatry, genetically pure samples of either species were found together with hybrids and
introgressant forms in several populations (Zelener et al., 2016).
Genetic diversity for esterases in the recently evolved stabilized
introgressant, Senecio vulgaris L.
However, the array of
introgressant markers was smaller than at Gaylord's site.
The detected additional variation originates from the
introgressant in the first scenario (Kesseli et al., 1991), while in the second scenario ancestral polymorphism (phylogenetic sorting: Soltis et al., 1992) clarifies the differences between the two sibling lineages L.
Plants closely related to domesticated plants and growing outside of cultivation may be: (1) ancestors of the domesticates; (2) escapes from cultivation, either identical to the domesticates or altered by generations of selection for existence in nature; (3) hybrids or
introgressants between a wild relative and the domesticate.
Because tea is an outcrossing species, clinal
introgressants extending from these two extremes are frequently observed, but these are still referred to as China or Assam teas depending on their morphological proximity with the main taxa (Wight, 1962; Banergee, 1992).
