Proportion of genomic inbreeding captured by homozygosity by descent segments computed with a predefined multi-class Hidden Markov Model (F_HBD) in each class. The proportion of F_HBD in each HBD class was computed in individuals from the high variability line (H-Line) and the low variability line (L-Line). The proportion of F_HBD is represented in intermediate generations (6, 7, 8 and 9) and in most recent generations of the selection experiment (23, 24, 25 and 26). F_{HBD_2}: genomic inbreeding coefficient obtained from homozygosity by descent probabilities (F_HBD) of age class 2. F_{HBD_4}: F_HBD of age class 4. F_{HBD_8}: F_HBD of age class 8. F_{HBD_16}: F_HBD of age class 16. F_{HBD_32}: F_HBD of age class 32. F_{HBD_64}: F_HBD of age class 64. F_{HBD_64}: F_HBD of age class 64. F_{HBD_128}: F_HBD of age class 128. F_{HBD_256}: F_HBD of age class 256. F_{HBD_512}: F_HBD of age class 512.
