PCA plot of the first and second components of a PCA applied to variants’ most probable dosage for 176 samples. The name of the parent samples (large points) is indicated next to the corresponding point, while progeny samples are indicated with smaller points. For parent samples, the suffix ‘T Rep. i’ represents technical replicates, while ‘B Rep. A’ represents biological replicates. For the progeny samples, the shape of the points represent the first parent (i.e. Crop20 or Crop52), and the colour the second parent
