Seven populations of Limnanthes alba were described for their rates of outbreeding, amount of genetic variability, and response to enforced selfing in terms of inbreeding depression. Outcrossing rates, estimated by using two genetic marker loci, varied between 43 and 97%. Heterozygosity level was found to be in the range of 12 and 27 percent, whereas percent polymorphic loci varied twofold (between 29 and 57%) among populations. Inbreeding depression was found to be significant in four of seven… 
A comparative study of floral and electrophoretic variation with life history variation in Limnanthes alba (Limnanthaceae)
TLDR
Plants derived from ten representative Limnanthes alba populations in Northern California, grown in a common environment, showed significant among-population genetic variation of certain floral and life history characters, suggesting selection may have predominated over certain neutral processes during the evolution of some floral andlife history characters.
Inbreeding depression under a competitive regime in Mimulus guttatus: consequences for potential male and female function
TLDR
Progeny resulting from selfing are smaller as adults and contribute significantly fewer potential gametes into the gene pool as pollen grains and ovules, suggesting relatively little differentiation between populations.

Estimation of the mating system in open-pollinated maize populations using isozyme polymorphisms.
TLDR
Isozyme variants were adopted as markers in this investigation because of their many advantages in studying such populational processes as the mating system and the results obtained when the method was applied to isozyme data from two open-pollinated populations of maize are presented.
