FigureS1 Interval mapping forQTL with effects on TBA, LS, PS, OR and TN on SSC5. Chromosome-widesignificancelevel at P<0.05 (broken red line) and P<0.01 (solid red line), genome-widesignificancelevel at P<0.05 (broken blue line)and P<0.01 (solid blue line). TBA, total born alive; LS, littersize; PS, prenatal survival; OR, ovulation rate; TN, teat number. 10 20 30 40 50 60 70 80 90 100 110 120 0 2 4 6 8 10 12 SW 41 3 SW R4 53 GD F1 1 DAG K S0 00 5 IG F1 SW 19 54 SW 96 7 F - v a l u e (v a r i a n c e r a ti o ) SSC5 - Marker positions and map length (cM) T BA LS PS OR TN 0 . 0 5 0 . 0 1 G 0 . 0 5 G 0 . 0 1
