Identification of synaptonemal complexes in postnatal oocytes from one-day-old puppies of domestic dog [Canis familiaris]

The present paper describes a synaptonemal complexes analysis carried out on oocytes collected from the ovaries of one-day-old puppies of domestic dog (Canis familiaris). Ovaries have been collected from 20 individuals altogether. Synaptonemal complexes were identified in oocytes originating from two puppies. It is concluded that the onset of canine female meiosis may occur earlier than previously reported.
