Similarities in the NULLO, SRY-α, BNK and SLAM proteins from Drosophila spp. a Drosophila suzukii NULLO (DsNULLO) is aligned with orthologs from Drosophila biarmipes [DbNULLO] (GenBank: XP_016948821.1), Drosophila melanogaster [DmNULLO] (GenBank: NP_511067.3), Drosophila rhopaloa [DrNULLO] (GenBank: XP_016982709.1), and Drosophila serrata [DserNULLO] (GenBank: XP_020805612.1). b Drosophila suzukii SERENDIPITY-α (DsSRY-α) is aligned with orthologs from Drosophila grimshawi [DgSRY-α] (GenBank: XP_001995347.1), Drosophila hydei [DhSRY-α] (GenBank: XP_023168708.1), Drosophila melanogaster [DmSRY-α] (GenBank: NP_524580.1) and Drosophila virilis [DvSRY-α] (GenBank: XP_002056142.1). c Drosophila suzukii BOTTLENECK (DsBNK) is aligned with orthologs from Drosophila melanogaster [DmBNK] (GenBank: NP_524604.2), Drosophila miranda [DmirBNK] (GenBank: XP_017140437.1), Drosophila obscura [DoBNK] (GenBank: XP_022213695.1), and Drosophila kikkawai [DkBNK] (GenBank: XP_017034088.1). d Drosophila suzukii SLOW-AS-MOLASSES (DsSLAM) is aligned with orthologs from Drosophila grimshawi [DgSLAM] (GenBank: XP_001988112.1), Drosophila pseudoobscura [DpSLAM] (GenBank: XP_001355861.2), Drosophila melanogaster [DmSLAM] (GenBank: NP_001285668.1), and Drosophila busckii [DbuSLAM] (GenBank: ALC38995.1). The protein alignment was performed in Geneious Prime program and similarities (Blosum45, threshold 1) are shown
