Summary
The lengths of the chromosomes during mitotic and meiotic cycles of the male germ cells ofAnacridium aegyptium L. (Orthoptera) have been measured: the shortening of the chromosomes was found to be about the same in the spermatogonial mitosis and in the 2nd meiotic division from prophase to metaphase (about 3:1); as well as from the premetaphase to the mid-metaphase of mitosis and from diplotene to the 1st metaphase of meiosis (about 2:1). In mitosis the longer chromosomes become shorter than the shorter ones; the contrary is true for zygotene to pachytene; the same in the other stages of meiosis.
