Figure 4 – The genetic load at UCEs of six pink pigeons
calculated using cross-mapped chCADD scores. Correlogram showing the
total load of potential offspring between six individuals of the captive
pink pigeon population. The colour of the tile is relative to the load
of the offspring when compared to other potential offspring, and it is
ranked on a gradient from high load (red) to low load (blue).(A) genetic load of the offspring between two potential
parents, (B) realised load and (C) masked load.(D) The genetic load (grey), realised load (blue) and masked
load (orange) of the hypothetical offspring of all possible crosses
(including “selfing”). (E) The distribution of total realised
load in the offspring generation calculated by crossing all individuals
at random. In this procedure, each individual was crossed twice without
self-mating or repeating the same crosses, and this was repeated 10,000
times. The optimal crossing combination is shown in blue.
