Does God shape your destiny by the genes you inherit? From the Christian perspective: Does God allow the process of recessive genes being over-powered by dominant genes to create who you are - personality traits, interests etc. - and then see how a person with your qualities would fit best in this world. . . thus, molding your destiny?
Calvinists are famous for their belief in double predestination. 


  Double predestination
  
  Calvinistic predestination is sometimes referred to as "double predestination."2 This is the view that God has determined the eternal destiny of every human being. He has chosen some to eternal life to be saved through the finished work of Christ, and foreordained others to everlasting punishment for their sin.


Hyper-Calvinists believe in Equal Ultimacy, which states that God actively forces everything to happen. I think this is what your question is asking about. In Equal Ultimacy, God would be forcing your genes into certain conformations and making you exactly what you are. 

The opposite view of Calvinism is Arminianism. No version of Arminianism has God directly forcing people to do anything. It leaves the responsibility of the most weighty thing - salvation - on the individual; likewise with the less weighty things. Your genetics would be said to come from your parents through a system which God started and continues by His power which is resisted by the devil. 


  Psalm 139:13
  For you created my inmost being;
     you knit me together in my mother’s womb.


From an Arminian perspective God's work in the earth and his ability to answer prayer also has something to do with your genetics.  

I'm Arminian so I blame my negative genetic traits on my parents and occasionally the devil, and I attribute my positive genetic traits to God as answered prayers.
