The Meiotic Chromosomes of twoMacaca

Abstract
In a study of the meiotic chromosomes of Macaca, the mean chiasma frequency has been found to be between 1.9 and 2.1. No instances of translocation or insertions were seen. It is suggested that the Y chromosome pairs with the terminal portion of the short arms of the X chromosome. The marked chromosome pair has been identified and its behavior, followed through meiosis, suggests that the achromatic zone has an inhibitory action on the formation of chiasmata.
