Linear regression of the generation number on the allele frequencies computed in each line. Allele frequencies were estimated in the two lines by combining, for each generation, individuals of the generation n with the previous ones (animals from generation G1 to G n-1). Allelic frequencies evolutions are reported for SNP-QTL corresponding to a no-evolution, b co-evolution in both lines, c opposite-evolution, and d evolution only in one line, situations
