TABLE 2.

Proportion of RPA foci and SC length of each bivalent at early pachytene, calculated over the number of foci and SC length of autosomes. Only cells in which all bivalents could be recorded have been included. Values are presented as mean ± standard deviation. n: number of cells analyzed; f = number of foci.
