種形成は新しい生物多様性の産生の基礎である。しかしながら、種形成過程において、自然選択がゲノムをどのように形作るのか、まだ多くを知らない部分がある。選択が障壁遺伝子座の遺伝子流動に作用し、生殖隔離を促進すると仮定する。しかしながら、遺伝子流動と選択の証拠はしばしば間接的なものであり、障壁遺伝子座の時間的安定性についてはほとんど知られていない。ここでは、一倍体二倍体を利用して、二種のクヌギアリの交雑種の候補雄障壁遺伝子座を特定する。アリの雄は一倍体であるため、ヘテロ接合の場合、二倍体の雌アリが隠性障壁遺伝子座を隠すことができるのに対し、彼らは隠性障壁遺伝子座を明らかにすると期待される。次に、10年後に収集したサンプルで障壁の安定性をテストし、生存解析を用いて候補雄障壁遺伝子座に作用する自然選択の直接的な測定値を得る。我々は、ゲノム全体に散在する複数の候補雄障壁遺伝子座を発見した。驚くべきことに、それらの一部は10年後には安定しておらず、その後のサンプルでは自然選択が明らかに進化に反対する状態から進化を支持する状態に変化した。浸透効果の不安定性と内向き対立遺伝子の自然選択は、環境に関連した選択によるものである可能性があり、自然選択の強度の時間的変化と、将来の種形成研究において仮定される障壁遺伝子座の障壁効果の安定性を考慮する必要性を強調している。
