Mating schematic for testing dCTCF for an effect on maternal establishment of the Dp(1;f)LJ9 imprint. Two primary sets of progeny and an external control were generated from this cross: progeny with a maternally-inherited Dp(1;f)LJ9 mini-X chromosome from mothers with the CTCF30 mutation (Mat-Est. CTCF30) and progeny that also have a maternally imprinted Dp(1;f)LJ9 chromosome but from mothers wild type for CTCF (Mat-Est. CTCF+). External control crosses were produced by crossing F1 generation X^X/Dp(1;f)LJ9; e/e females to y1zag53d/Y males (not depicted).
