Chromosomes

“…Light microscopic observations on chromosomes of Tradescantia (NEBEL, 1958), of Hyacinthus (SORSA and SORSA, 1968) and particularly of endosperms of Haemanthus (BAJER, 1965) leave no doubt that the chromatids appear divided in two or even more strands. TAKAYAMA, 1973) are obviously based on a false interpretation of the microscopic picture. In this connection it should be remembered that ZWEIDLER (1964) found two semiconservative replicating subunits per chromatid in Allium cepa.…”
