Table 2: The bcd intron 2 sequences of 12 blowfly species: Drosophila melanogaster and Musca domestica.

  538051.tab.002  

Single-nucleotide polymorphism: R = A or G; Y = C or T; W = A or T; M = A or C; K = G or T; M = A or C.
The underlined nucleotide(s), for example, AA stand for the two alleles of AA versus deletion (-).
: sample size.
*For the intron 2 analysis, an additional sequence of the bcd gene in L. sericata (GU979856) was included.
L. ampullacea had an eight-nucleotide insertion in one individual at position 21 (indicated with slash symbol (/)).
