Mapping of two alleles of the cloche mutant. (A) Homozygosity scoring of the clo ^s5 and clo ^m39 alleles reveals corresponding overlapping peaks on chromosome 13, where the mutation has been previously mapped. (B) Sequence pileup of the clo ^m39 allele confirms the previously established deletion and reveals the boundaries of the deletion interval. (C) Log likelihood scoring of the clo ^s5 alleles achieves a higher resolution of the mutation region with a narrower interval than the homozygosity scoring method.
