COPEPODEN - A TEST OBJECT OF CLASSICAL CY TOGENETICS AT THE BEGINNINGOF THE 20TH-CENTURY

During the first decades of the twentieth century the research on cope pods raised great biological interest in Germany. The special merit of the zoologist and geneticist VALENTIN HAECKER (1864-1927) and his pup ils was to focus again on these animals in scientific research. In num erous publications they presented their results about reduction, group ing, conjugation of chromosomes and especially, about zytology and mor phology of the cope pods. Research on copepods united the arguments of WEISMANN and MENDELian genetics. This research also has shown that co pepods display the same genetic and cytological phenomena as the class ical research objekt Ascaris megalocephala bivalens.
