Loss of Blm decreases mean and maximum lifespan. (a) Kaplan-Meyer survival curves for homozygous wild-type, lig4, and blm females. Number of individuals: wild type = 218, lig4 = 218, blm = 216. (b) Survival curves for homozygous wild-type, lig4, and blm males. Number of individuals: wild type = 198, lig4 = 189, blm = 200. All individuals were unmated. Two independent replicates of these experiments gave similar results.
