What would the plot of offspring beak depth against parental beak depth look like?

As there is an absence of a connection between's the mouth profundity of the parent and that of the posterity, there is no example in the chart above. The focuses are conveyed haphazardly to demonstrate that guardians with more profound bills don't really deliver posterity with more profound than normal snouts. Therefore, since there is no connection between's the mouths of guardians and their posterity, we can state that there is no heritability, which disregards Darwin's third proposed and would derive that there is no choice.
