Much stress has been laid by some authors on the supposed fact, that →mongrel animals alone are born closely like one of their parents; but →it can be shown that this does sometimes occur with

I entirely agree with Dr. Prosper Lucas, who, after arranging an enormous body of facts with respect to animals, comes to the conclusion, that the laws of resemblance of the child to its parents are the same, whether the two parents differ
