Has anyone ever told you that you act just like your mother or father? Most of us have experienced this and hated it. There is good news though; you might not be able to help it! Recent studies have shown that personality could be related to your genes!
In identical twins, personality is considered to be 46% genetic, while in fraternal twins, personality is considered to be only 23% genetic. This is easier to determine because they share many of the same genes. Now, what about everyone else? This is a much tougher question.
How genes are expressed has a lot to do with personality differences. Though a person may have inherited certain personality traits from their mother or father, they may not be expressed the same way. There is a lot of research being done on how genes are expressed-- which genes are on or off when and why etc. Until gene expression is completely understood, a clear answer about genes influencing personality cannot be given.
