This study was undertaken with an aim to define criteria of normality for meiosis by assessing the frequency of meiotic prophase cell types, the frequency of pachytene substages in normal and abnormal spermatogenesis and to determine what synaptonemal complex (SC) abnormalities are found in normal and abnormal meiotic prophase and their frequencies.
Products of the genes HOP1, required for synaptonemal complex formation and recombination, and ZIP1, essential for synapsis, have been localized to meiotic chromosomes and as a part of the central component of the synaptonemal complex, respectively (Hollingsworth et al., 1990; Sym et al., 1993).
Synaptonemal complex data were not collected from this animal, and thus, no definitive statement can be made regarding the early meiotic behavior of this chromosomal combination.
