Correlation between number-of-integrations, ALVE mRNA expression levels and body weight in F
birds from the advanced intercross line. Each dot in the plots represents an individual of F9 generation. A. Plot based on mRNA expression levels against ALVE integration number in 80 F9 birds. P < 0.05 for correlation coefficient r = 0.28 including all points as shown in panel A. P < 0.001 for correlation coefficient r = 0.41 when one deviating data point (black diamond) was omitted from the analysis. B. Plot based on body weight against the number of ALVE integration in 80 F9 birds. P < 0.5 for correlation coefficient. C and D. Correlation between the body weight and the ALVE expression in F9 birds from the advanced intercross line. Open-circled data points indicate individuals of which env cDNA fragments (amplicon e* in figure 1C) were sequenced in order to find out sequence variant. C. Plot based on 42 F9 male chickens. P < 0.22 for the correlation coefficient. D. Plot based on 38 F9 female chickens. P < 0.01 for the correlation coefficient. H, HWS-variant; L, LWS-variant.
