Subject: l(4)102CDh lines
For the l(4)102CDh analysis, the following fly lines were used: l(4)102CDh
\#2704 from BG (now listed as l(4)102CDh-1 \#4041 at Midamerica), l(4)102CDh2
\#87200, and l(4)102CDh* \#73680 both from the Umea stock center.
I tested these l(4)102CDh lines for allelic complementation and found that
all three lines survive over one another. Therefore, it is highly unlikely
that the three lines represent the same complementation group. Line \#4041
does not survive over \#2704 confirming that these are the same line
according to the stock center.
My further complementation analysis used lines \#2704, \#87200 & \#73680.
Complementation analysis of ey recessive alleles, eyR and ey2, with the
l(4)102CDh lines demonstrate that the l(4)102CDh lines should not be listed
as ey alleles without specific evidence showing that they are ey alleles.
None of the l(4)102CDh lines show lethality or a reduced eye phenotype over
these recessive ey alleles. In addition, all three lethal lines survive
over eyD, a suspected dominant ey allele which is homozygous lethal, and do
not exhibit any exacerbation of the eye phenotype normally seen with eyD/+.
All three l(4)102CDh lines survive over Df(4)G.
