On basis data their statistical analyses, each stage subdivided two substages.Frequency distributions oocyte diameters present a characteristic for (sub)stage. McCall units were calculated from frequency distribution 3. This is reference other or substage used as any group animals species under examination. transformations allow comparison distributions. It concluded that diameter reliable parameter delineating oogenesis rubens, but detailed description annual required analysis complex variables, including correlations among the...
