why every person is different in this world?

why?

You have ever noticed why , everyone are not same or identical? is there is possibilities of clone of your face , body etc ? 

 

 So probably the answer is NO. it is possible to have clone but condition the young one must be twin brothers/sisters

So why we not look alike our parents..

There is very simple logic as we all know , our unit of life is DNA , and DNA along with HISTONE (a kind of protein which bind DNA to form CHROMOSOMES ) form chromosomes and on chromosomes present GENES (also known as codding on DNA as a nitrogenous bases). 

These genes are the hereditary character which is responsible for showing each character of our body. We are different from our parents because of the process CROSSING OVER of chromosomes. here female and male  chromosomes cross each other to recombine there character to form new character as baby or the young one produce. 

 

 This leads to new recombination and young one produce are different from there parents. IN SOME CASES THE PROCESS FAILS AND THE CHILD LOOK ALIKE SAME AS HIS/HER PARENTS ARE.

According to some theories a person have 7 clones in this world.,but it is not accepted because of not proof evidences.

 In humans there 23 pairs of chromosomes almost 46, and in our reproductive cells (ova , sperm) 23 chromosomes , on fusion of sex cells 46 chromosomes restores.Every chromosomes have their different function.  

Proteins are also formed by the genes  of  the chromosomes. 

 THIS IS THE REASON WHY EVERY ONE IS NOT ALIKE .
