Figure 2From: Distinct gene loci control the host response to influenza H1N1 virus infection in a time-dependent mannerPrincipal component analysis of all body weight traits reveals two distinct groups. PCA loading plot of principal components PC1 and PC2 (Supplement Figure 2) for body weight traits form day 1 to day 7 p.i. shows two distinct groups. The variation of body weight loss at day 3 to day 7 (ID 13007 to ID 13011) are mainly represented by factor 1. On the other hand, variation of body weight loss at day 1 (ID 13005) and 2 (ID 13006) are most likely explained by factor 2.Back to article page
