Figure 5. .

Histograms of the distribution of MLH1 on chromosomal bivalent 11. The X-axis indicates the position (in μm) of MLH1 foci along the length of the bivalent. The position of the centromere is indicated by a small blackened circle; the p arm lies to the left, and the q arm lies to the right. The Y-axis indicates the number of MLH1 foci mapped to each interval. A, Distribution of MLH1 on bivalents with only one MLH1 focus. B, Distribution of MLH1 on bivalents with two foci. C, Distribution of MLH1 on bivalents with three foci. D, Distribution of MLH1 on the single bivalent with four foci.
