| Abstract: | Quadrivalents, represented by unique synaptonemal complex configurations, together with normal bivalents are observed for the first time in a mammalian tetraploid pachytene spermatocyte prepared by microspreading. The chromosomal axes (lateral elements) clearly demonstrate the switching of partners in the quadrivalents as predicted from classical cytogenetic theory. Tetraploid formation, possibly by nuclear fusion, must have occurred prior to meiotic prophase. |
