The deletion uncovers the nuclease hypersensitive region, continuing proximally towards the iab-4 region.
Lesion in the Mcp region of the bithorax complex. DNA segment of approximately 2.8kb extending from position +92.5 to 95.5kb.
A4 is transformed to A5 identity and is a darkly pigmented.
Abd-BMcp-H27/Abd-BMcp-H27 is a non-suppressor of visible | recessive phenotype of brkMcp
Abd-BMcp-H27/Abd-BMcp-H27 is a non-suppressor of wing phenotype of brkMcp
The penetrance of the wing defect phenotype caused by brkMcp is unaffected if the animals are also homozygous for Abd-BMcp-H27.
