Are genes that are probably going to show themselves in a person.

if ur question is if genes can mutate or change then yes

Explanation:

Gene duplication was the first mechanism of gene generation to be suggested (Ohno, 1970), and this process does indeed appear to be the most common way of creating new genes. ... For example, more than 100 genes duplicate in the human genome per 1 million years (Hahn et al., 2007a).
