Cytology
Description

Imprecise excision allele generated by mobilizing P{SUPor-P}mhKG05829, resulting in a deletion within mh ( X:15 ,473,451..15,476,522, release 6) with an addition of 2nt of filler sequences.

Comment:

3072 bp deletion resulting from the imprecise excision of P{SUPor-P}mhKG05829. The deletion was reported to map to X:15 ,473,451..15,476,522 in R5 coordinates but they are actually R6 coordinates.

      Embryos from mh18 homozygous females lose their paternal chromosomes during and after the first zygotic mitosis, during the subsequent haploid mitoses the embryos show various degrees of aneuploidy, condensation and segregation defects.

      Comments

      The maternal-effect lethality of progeny of mh18 homozygotes as well as all trans-heterozygous combinations of mh1, mh9, mh31, mh18, mh6 and Df(1)shtdEPDelta can be rescued by combination with either mh+t5.8 or mhEGFP.
