  1. Ingenuity Pathway Analysis (IPA) of 221 “Analysis Ready” (AR) and differentially expressed (DE; FDR ≤ 0.05) (AR-DE) genes from riboflavin-rescued (Rf+) and riboflavin-deficient (Rf-) chickens on embryonic day 13 (e13). P-values were determined by IPA using Fisher’s Exact Test and represent the likelihood that AR-DE genes are over-represented and associated with a particular biological process or pathway. The percent overlap and ratios were calculated for the number of observed AR genes compared to the number of known genes for that category represented in the Ingenuity® Knowledge Base
