The analysis of the meiotic behaviour of the PMCs ofDipcadi serotinum(Liliaceae) (2n= 8 + 0–4 B) revealed an unusually high frequency of several types of abnormalities: chromosome breakage, pairing failure of chromosomes, irregular anaphase segregations etc. The possible origin of these meiotic abnormalities is discussed in relation to other characteristics of the genetic system of this species, as the existence of gene duplication phenomena.
