Mitotic recombination stocks

These stocks can be used in experiments to monitor induced or spontaneous mitotic recombination. They contain mutations or chromosomal duplications that change the color or morphology of cuticular structures derived from imaginal disks.

As shown in the figure, mitotic clones can be detected when recessive marker mutations are made homozygous by somatic recombination.


These stocks provide recessive mutations on each arm of the second and third chromosomes that change bristle morphology.


Both twin spots can be revealed by marking a chromosome with a recessive marker and a duplicated gene as shown below.  


These stocks carry the following transgene insertions or chromosomal duplications to rescue loss-of-function mutations affecting bristle morphology or color.

Duplicated gene
Transgene insertion or chromosomal duplication

Note that both chromosomes of the reciprocal translocation T(1;2)sc[S2] must be present for flies to survive. We suggest you review previous experiments that have used it before undertaking experiments.

Some stocks have markers for assaying recombination on multiple arms simultaneously.
