Yes, since the mean of 10mm and 6mm is different from the mean of 8 mm and 10mm. The offspring beak depth in this case would be about 8mm.

Work Step by Step

The correlation shown is between offspring beak depth and mean beak depth for the parents, and the slope of the line is about 1, so offspring beak depth is about the same as the mean for the two parents=10mm+6mm/2=8mm.
