Do people who look alike have similar personalities?

I did this by comparing the personality similarities and self-esteem of 23 unrelated look-alike pairs. I call them U-LAs.
Why are no two humans the same?
No two humans are genetically identical. Even monozygotic twins (who develop from one zygote) have infrequent genetic differences due to mutations occurring during development and gene copy-number variation.
What is a personality twin?
In study after study, twins have been found to have very similar personalities. This theory seems to point to a mixture of nature and nurture in the development of the human personality. For example, if one twin is more naturally introverted, then the other twin is likely to share this tendency.
Why no 2 are exactly alike even monozygotic twins differ from each other?
Environmental Differences While identical twins form with the same set of genes, human development is not just genetic. The environment also has an impact. 1 So, beginning in the early environment of the womb, external influences can change the appearance of twins. For example, some monozygotic twins share a placenta.

Though, the reason you can predetermine the actions of others may relate to the fact that we, as human beings, can actually smell personality types of others.
Are some traits more genetically similar to each other than others?
Some traits may have different underlying genetic causes. For example, white skin may be the result of one of three different genes. Two white people may look more similar to one another than to someone who is black, Asian, or what have you, but in that aspect be no more genetically similar.
