Together, the three modes of geitonogamy make a much larger contribution to self-fertilization than autogamy. Consequently, the genetic structure of this species is likely to be shaped by rare outcrossing events among colonists, followed by generations of self-fertilization to produce recombinant inbred lineages. Derivatives self-fertilized adjective ... We used production of self-fertilized eggs as an indicator of reproductive maturity in order to select individuals for our experiments. Johannsen further developed the pure-line concept and its relation to improving self-fertilized crops. Third, all of the self-fertilized progeny from all the individuals growing in a specific environment were identical to each other, but different from all the progeny of individuals grown in a different environment. self-fertilizing /sɛlfˈfəːtɪˌlʌɪzɪŋ/ adjective ... It has a 4-day life cycle and propagates as self-fertilizing hermaphrodites or by outcrossing after the spontaneous generation of males. Consider two closely related plant taxa, one of which is self-fertilizing and the other outbreeding. Hence, selection at linked sites is likely to be an important determinant of neutral polymorphism patterns within partially self-fertilizing species.
