Chromosome lengths in synthetic maps as a percentage of the lengths in the consensus mapb


Mean ± SD

98.7 ± 9.4%

103.9 ± 8.4%

96.5 ± 6.2%

Range

79.1–108.8%

a The base (reference) maps selected by PhenoMap were: Clipper/Sahara (1H), Yerong/Franklin (2H), Clipper/Sahara (3H), Dayton/Zhepi2 (4H), Barque-73/CPI71284-48 (5H, 6H) and Dayton/Zhepi2 (7H).

b The values reported are averages across chromosomes. Eighty-five loci not assayed in the seven populations used to construct the synthetic maps (Table 3) were removed from the JoinMap/perl consensus map before the comparison.
