This file has the raw data used for analysis of recombination rate with maternal age (crudely dichotomized as "young" vs. "old" as specified in the paper). Each row identifies whether a single pair of markers specified were recombinant (1) or not (0) in a single fly, so each fly studied is represented by many rows. File is large: 170,272 rows. To look for "food batch" effects, the vial from which the mother and grandmother were derived is also denoted. "Young" corresponds roughly to post-eclosion adult day 7-10 of life and day 7-17 of life for grandmother and mother (the F1 female), respectively. "Old" corresponds roughly to adult day 10-17 of life and day 17-24 of life for grandmother and mother, respectively.
