title: The pachytene chromomere map of the oocyte of the Turkish hamster (Mesocricetus brandti).
abstract: A study of the chromomere maps of the sex and twenty autosomal bivalents of Turkish hamster pachytene oocytes was carried out. The average total number of chromomeres in early/mid pachytene autosomes was 280 with 91 on the p (short arm) and 189 on the q (long arm). The submetacentric X1 chromosome had 20 chromomeres and the metacentric X2 had 27. Comparisons of the number and location of oocyte chromomeres are made with the pachytene spermatocyte chromomere maps of this species.
