Detailed Description

Statement

Reference

Shows lethality from the first to third larval instar when heterozygous with the MBT chromosome. Brain tumours are seen.

(Riede, 2001)

Lethal and tumour inducing over the MBT chromosome. Homozygotes die during the third larval instar. mer^pi9/mer¹⁴ animals are viable. Homozygotes show the formation of melanotic tumours. Gaps in somatic pairing are seen in the polytene chromosomes of heterozygous salivary glands. Heterozygotes show resistance to 1mM methyl methanesulfonate but not to 5mM hydroxyurea.

(Riede, 2000)

Shows strong somatic pairing defect in the salivary chromosomes. Causes significant melanotic tumor formation in larvae. Shows tumor formation when heterozygous with the MBT chromosome. Lethal when heterozygous with the MBT chromosome.
