Figure 8From: 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 the paternal 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 paternally-transmitted Dp(1;f)LJ9 mini-X chromosome from fathers with the CTCF30mutation (Pat-Est. CTCF30) and progeny that also have a paternally imprinted Dp(1;f)LJ9 mini-X chromosome but from fathers wild type for CTCF (Pat-Est. CTCF+). External control crosses were produced by crossing F1 generation X^Y/Dp(1;f)LJ9; e/e males to y1zag53d/y1zag53dfemales (not depicted).Back to article page
