Résumé

The chromosomes of three species of lower chordates were examined using a squash technique on small pieces of testis. Ciona intestinalis, a tunicate of the order Enterogona, has fourteen pairs of minute chromosomes. Styela plicata, a tunicate of the order Pleurogona, has sixteen pairs of chromosomes whose total size is approximately twice that of the Ciona chromosomes and about 10% of that of a typical mammalian complement. The hagfish, Eptatretus stoutii, of the suborder Myxinoidea, order Cyclostomata, has twenty-four pairs of chromosomes and what appear to be one to four small supernumeraries in some animals. The hagfish chromosomes are large, approaching the size of a typical mammalian complement. These size relationships agree in general with a concept of a small ancestral vertebrate genome which evolved into the larger present day genomes through a series of duplications of genetic material.
