With all the evidence in the field of dog breeding in relation to personality, how does that effect humans?

Question

Genetic diveresity has been proven to reduce disease and prolong longeveity in dogs. It also has mixed results such as a obsessive border collie mixed with hyper terrier can have bad results. Are people the same do we posses lineage of genes that enable our personality? In other words are there humans thats genetically just dont mix well such as an african and a full irish woman? Or is it random regardless of race will race only predict appearance and physcical charcteristics? is personality inherited through both parents gene pool? In time

will humans genetic diversity be so mixed in that we will become less resistant to disease and mental ilness?

Answer 1

Human races are not the same as breeds of dogs.  The behavior of many animals is a mix of instinct (from genetics) and training during raising (the environment).

Each race contains a very wide diversity, much wider than the diversity found in a canine breed.  This is true for mental and emotional traits as well as physical traits.

Personality seems to be more a function of the environment of the human child than of the genetics.  Any child raised with love will be much different personality-wise, than a child raised with indifference or abuse.  This has been studied through "separated at birth twins" in humans.

Mental illness in many humans seems to be more environmental than genetic.  There are exceptions to this but these are minor in comparison to the over-all human population.   How society deals with the mentally and emotionally unbalanced is the measure of how great a society is.  The USA is considered  poor society by most professional and moral standards.
