Popis:	Various chromosomal types were obtained from a hypotetraploid (2n=35) of M. chamomilla L, isolated from the progeny of an induced autotetraploid plant. Karyological analysis reveals preferential transmission of small subterminal chromosomes as these are never eliminated in any of the aneuploids obtained. The absence of 3 median chromosomes from the fourth quadriplex of the plant with 2n=33 seems to boost multivalent frequency and also accentuates desynapsis caused by high temperature.
