Figure 7From: The Drosophila homolog of the mammalian imprint regulator, CTCF, maintains the maternal genomic imprint in Drosophila melanogasterMating 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 CTCF30mutation (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).Back to article page
