Abstract
The distribution of interchange heterozygotes is analysed in one population of each of three species in the tribeAloïneae (Liliaceae). While one population is shown to be clonal the other two indicate that natural selection eliminates interchange homozygotes and maintains the chromosomal uniformity of the tribe. Analysis of a fourth population containing aneuploids and chromosome deletions shows that mutant plants are capable of interbreeding, but that spread of the aberrations is limited.
