Fig 72 Growth of the nucleus during meiosis in the amphibian egg, showing the 

 enlarged germinal vesicle and diplotene lamp-brush chromosomes with lateral oops. 

 (A) Early diplotene nucleus of the frog. (B, C, E) Different phases of the diplotene 

 nucleus in this form. These figures are based upon data provided by Duryee ( 50 and 

 sections of the frog ovary. (D) Drawing of the unfixed germinal vesicle of Tritums. 

 Some aspects of the attenuate chromatin threads with lateral loops are shown. The 

 nucleoli are numerous and occupy the peripheral region of the germinal vesicle. (F) 

 Semidiagrammatic drawing of the later phases of the developing frog egg. It shows the 

 germinal vesicle assuming a polar condition, with the initial appearance of germinal 

 vesicle shrinkage before the final dissolution of the nuclear membrane. Observe that the 

 chromosomes are contracting and now occupy the center of the germinal vesicle.
