Homozygous flies appear healthy, have normal viability and can be maintained as a homozygous stock.
The polytene X chromosome from the salivary glands of homozygous male larvae variably has perturbed morphology.
Flies homozygous for Dp(2;2)BEAF-32A-KO (which carries the BEAF-32A-KO.5' and BEAF-32A-KO.3' alleles) are viable. They appear healthy, have normal viability and can be maintained as a homozygous stock.
