incompatibility - (1) In flowering plants, failure to set seed (i.e. of fertilization and subsequent development of embryo) after pollination (self or cross) has taken place. Due to inability of pollen tubes to grow down style. In physiologically heterothallic fungi, failure to reproduce sexually in single or paired cultures. In both cases the incompatibility is genetically determined - it is due to the possession by the individual plants or thalli of genes which prevent the fusion of likes; and the result is the same, namely, to promote outbreeding.
