Ovary histopathology of the Dmc1Mei11/Dmc+ and Dmc1Mei11/Dmc1tm1Jcs mice

endocrine/exocrine glands
• 60% of females exhibit a relatively normal ovarian morphology with developing and antral-stage follicles, although with fewer follicles than in wild-type
• 40% of females exhibit residual ovaries devoid of follicles

reproductive system
• spermatocytes exhibit either a zygotene-like or aberrant pachytene-like morphology, containing a mixture of synapsed, partially synapsed and asynapsed chromosomes
• 60% of females exhibit a relatively normal ovarian morphology with developing and antral-stage follicles, although with fewer follicles than in wild-type
• 40% of females exhibit residual ovaries devoid of follicles
• testes undergo complete prophase I meiotic arrest, without signs of postmeiotic differentiation as is seen in heterozygous Dmc1Mei11 males
• defective chromosome synapsis and double strand break repair in spermatocytes; spermatocytes exhibit either a zygotene-like or aberrant pachytene-like morphology, containing a mixture of synapsed, partially synapsed and asynapsed chromosomes
