Abstract:
In the oocytes of Macacus rhesus the mitochondria are granular in nature. The juxta-nuclear stage of mitochondria gives rise to perinuclear rings. Later a clear archoplasm is observed. When the egg grows in size and age, the layer of mitochondria breaks up into large number of patches, which arrange themselves in the form of a peripheral band. Later, these patches are observed scattered in the whole cytoplasm. In Canis familiaris the mitochondria) aggregation is at first at the juxta-nuclear position; then they are seen concentrated at the yolk-nucleus area. Later, the mitochondria increase in number so much on one side that the nucleus is pushed away from the centre and becomes eccentric. The mitochondria, in the initial stages, are granular, but in advanced oocytes, they become finer and dust-like. Soon the cap of dust-like mitochondria disintegrates and the mitochondria are seen uniformly distributed in the ooplasm.
