  • Three dicentric inducible chromosomes were used to analyze the transmission frequency of TD chromosomes through the male germline. TD chromosomes are identified by loss of a distal marker: (A) BS from DcY(H1); (B) w+ from Dc3Lt; or (C) by lack of a dicentric inducible small rough-eye phenotype when crossed to a P{ey4x-FLP.Exel}1 located on chromosome 3.
