The following list of four Drosophila mutations indicates the symbol for the mutation, the name of the
gene, and the mutant phenotype:
Allele symbol Gene name Mutant phenotype
dwp dwarp small body, warped wings
rmp rumpled deranged bristles
pld pallid pale wings
rv raven dark eyes and bodies
You perform the following crosses with the indicated
results:
Cross #1: dwarp, rumpled females × pallid, raven males
→ dwarp, rumpled males and wild-type females
Cross #2: pallid, raven females × dwarp, rumpled males
→ pallid, raven males and wild-type females
F1 females from cross #1 were crossed to males from
a true-breeding dwarp rumpled pallid raven stock.
The 1000 progeny obtained were as follows:
pallid 3
pallid, raven 428
pallid, raven, rumpled 48
pallid, rumpled 23
dwarp, raven 22
dwarp, raven, rumpled 2
dwarp, rumpled 427
dwarp 47
Indicate the best map for these four genes, including
all relevant data. Calculate interference values where
appropriate.
