Mutation that disrupts the splice acceptor site at the intron1-exon2 junction.
An unspecified point mutation in the intron 1/exon 2 splice acceptor site. The splice site mutation has been arbitrarily mapped by a FlyBase curator to the first base of the splice acceptor site.
Homozygous flies have ommatidia containing an extra photoreceptor.
Selected as: A mutation that survives at 25[o]C in the presence of Scer\GAL4ey.PH (the progenitor Dip3C00008 allele results in lethality when expressed under the control of Scer\GAL4ey.PH at 25[o]C).
