The evolutionary stability of outcrossing, despite the strong selective advantage of genes increasing self-fertilization (Fisher 1941; Nagylaki 1976), is attributable to the high inbreeding depression maintained by deleterious recessive mutations in habitually large, outcrossing populations, and the fact that self-fertilization usually evolves polygenically, by small increments (Jain 1976; Lande and Schemske 1985; Charlesworth and Charlesworth 1987; D.
Morphological variation may not reliably reflect the real genetic variation because of genotype-environment interaction and largely unknown genetic control of polygenically inherited morphological and agronomic traits (Smith and Smith, 1992).
Quantitative traits such as these are determined polygenically.
