Different kids of the same parents have different genetics. When people have kids that aren't twins, each kid has a uniquely different combinations of genes, which could result in differing personalities as a result of inheriting a different combination of genes from the same two parents. Of course, people's personalities are influenced by their home life, their experience at schools, and their experience growing up with siblings (which is different amongst kids of the same parents) among a huge range of other variables. I suppose the making of an entrepreneur is similar.
