Question

To what extent is the concept of family dependent on hereditary connections versus emotional ones?

Answer 1

With hereditary connections that is what you look like and what phenotype you could have gotten from your mom or your dad.
But on the other hand versus the emotional ones no one could take a dna test to figure out if you are going to be sad or happy, but you could take a dna test to see which genotypes you have to see if they are the same or similar to your parents, but like I said before you can’t do that with emotions.
