Abstract

The spermatogenesis of five guinea‐pigs was studied. The spermatogonial chromosome number is approximately sixty‐two plus or minus two. The primary spermatocyte number is approximately thirty‐one. The spermatogonial number in the early prophase is lower than it is in later stages. This condition is due to late fragmentation of the large chromosomes found in the earlier stage. A possible sex chromosome of the X‐Y type may be identified. Its components segregate during the first maturation division.
