|
|
• despite an absence of synapsis between homologs in spermatocytes, 28%-35% of spermatocytes exhibit homolog pairing in the chromosome mid- and subtelomeric regions
|
|
|
• no spematocyte nuclei with 19 fully synapsed autosomes are detected
(J:94208)
• regional splitting of axial elements is seen at the early zygotene stage but is suppressed in later stages when double-strand break markers accumulate in spermatocytes
(J:209347)
|
|
|
• spermatogenesis arrests at meiotic prophase I with no postmeiotic spermatids seen in the seminiferous tubules
(J:94208)
• spermatocytes form axial elements but they arrest at the leptotene/zygotene stage
(J:209347)
|
|
|
• spermatocytes form axial elements but they arrest at the leptotene/zygotene stage with aberrant synaptonemal complex formation
|
 |
• only residual ovaries are seen in 6 week old females
|
|
|
• at 5-6 weeks of age mutant testis are about 50% the size of wild-type
|
|
• both males and females are infertile
