Figure 6
Mating schematic for testing the effect of dCTCF on the maintenance of the Dp(1;f)LJ9 imprint. Two sets of progeny are generated from this cross: progeny that have independently inherited the Dp(1;f)LJ9 mini-X chromosome and a CTCFXmutant allele (modifier progeny) and progeny that have inherited Dp(1;f)LJ9 and the TM3, Sb Ser balancer, but had a parent carrying a CTCFXmutant allele (maternal and paternal effect test progeny).
