N, number of individuals; P, pure Culex pipiens; Q, pure Culex quinquefasciatus; H, hybrids between the pure groups (Culex pipiens and Culex quinquefasciatus); F1, hybrid first generation; F2, hybrids second generation; BxP, backcross Culex pipiens; BxQ, backcross Culex quinquefasciatus, H′, hybrids defined by the sum of assignment probabilities for all hybrid classes.
Values in parenthesis refer to the frequencies (in percentage) within each cluster.
