Kinetic behaviour of autosomes in meiotic cells of Myrmus miriformis Fn. (Corizidae, Hemiptera) was followed by using a naturally occurring satellite‐like element to mark one telomere of an autosome. It was found that the telomere, being kinetically active during the first meiotic division, is kinetically inactive during the second division, suggesting dikinetic nature of meiotic chromosomes. To explain the kinetic behaviour of holokinetic chromosomes in different cell types, a hypothesis is advanced according to which differences in kinetic behaviour reflect differences in structural organization of the axial system in a chromosome.
