role of homoploid hybridization in evolution: A century of studies synthesizing genetics and ecology by Yakimowski, Sarah B, Rieseberg, Loren H

“…While homoploid hybridization was viewed as maladaptive by zoologists, the possibility that it might play a creative role in evolution was explored and debated…”

Ecological genetics of sex ratios in plant populations by Barrett, Spencer C. H., Yakimowski, Sarah B., Field, David L., Pickup, Melinda

“…In many angiosperm species, populations are reproductively subdivided into distinct sexual morphs including females, males and hermaphrodites. Sexual…”

The role of hybridization in the evolution of sexual system diversity in a clonal, aquatic plant by Yakimowski, Sarah B., Barrett, Spencer C. H.

“…The stable coexistence within populations of females, males, and hermaphrodites (subdioecy) is enigmatic because theoretical models indicate that maintenance…”
