Conditional mammary Sod2 knock-out mothers bear normal numbers of healthy pups and sustain multiple litters. (A) Average counts of number of pups per litter throughout reproductive lifetime in Sod2^L/L and Sod2^−/− mice. Black bar = Sod2^L/L, Grey bar = Sod2^−/−. (B) Average weight per pup at varying time points until weaning. Black bar = Sod2^L/L, Grey bar = Sod2^−/−. Six mice per experiment were analysed; data are shown as mean and s.d.
