Figure 1.

xnd-1 exhibits a mortal germ line phenotype. (A) Heat map depicts brood sizes of 12 lines (columns) from 10 independent xnd-1 F1s (rows) for indicated generations. Assay was performed as described in Materials and Methods. (B) Average brood sizes from fertile lines depicted in (A) over generations indicated. Both ok708 and ok709 alleles are presented and are phenotypically similar (Wagner et al. 2010). All other analyses are performed with ok709.
