¹The haplotypes are formed by microsatellite markers (MCST96O22, UMNP891, MCSE347J6, SW1522, UMNP93, UMNP870, MCSI0244D12) within the interval of interest.
²Maternal haplotypes in bold are common to F₁ females from both 0F11 and 0F21 families. The number between brackets represents the haplotype over the core UMNP891-UMNP93 interval.
³The p_r values are determined after removing the haplotypes with <30 meioses.
