PLATE 6 
EXPLANATION OF FIGURES 
Lateral views of first spermatocyte metaphase complexes from atypical 
individual 2511- 
52 to 56 Complexes with the three extra homologues (S). Note that in each 
cell two of the extra dyads have conjugated to form a tetrad and that the other 
remains free and segregates independently, If the extra dyad is passing to the 
same pole as the accessory, it is placed above the tetrad; if to the opposite pole, 
below the tetrad. 
57 to 61 Complexes cbntaining the extra tetrad (S).
