Correlation between number-of-integrations, ALVE mRNA expression levels and body weight in F₉ 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.
