Figure 5.—

Repeat regions of the four microsatellite loci are mapped onto phylogeny of the silkmoths. The number of repeat units is indicated as subscripts. The allele sizes (in base pairs) are given in parentheses. Note that the number of alleles sequenced differs between species. NA indicates no PCR amplification and ND represents alleles for which sequence could not be determined. Subscript .. represents imperfections introduced in the repeat motif by mutations, the number and sequence of which can vary between different alleles. Superscript $ denotes duplication of 59-bp region containing (GT) repeat motif in one of the alleles of A. pernyi, and * represents creation of a new repeat motif by point mutations. Phylogeny of domestic silkmoth, wild silkmoths, and bollworm is based on 12S rRNA sequence of 430 bp. D. nasuta is used as an outgroup; bootstrap values are mentioned above the node (our unpublished data).
