Abstract

Examples of zygotene chromosomal configurations in Allium senescens subsp. montanum are presented. Bivalents do not dominate in a zygotene stadium. Some bivalent segments show deletions. Also, tri- and tetravalents segments are observed. The conjugation of SAT-chromosome shows that a translocation has occurred in the SAT segment. In addition, univalents indicate that meiotic behaviour of the species is unstable.
