1 Due to a missing or defective enzyme, children with PKU cannot process a part of a protein called phenylalanine. 2  Without treatment, phenylalanine builds up in the blood and causes intellectual disability. 3  Down syndrome is an example of a chromosomal disorder. There are many genetic diseases associated with intellectual disability. 2  Some examples include PKU (phenylketonuria), a single gene disorder. 3  Due to a missing or defective enzyme, children with PKU cannot process a part of a protein called phenylalanine.

From the graphic one can see that it looks like a wave, and in truth sines (and cosines) come as solutions of a number of wave equations, where the variable is a function of space and time. here phi ($\phi$) is a phase . It is a constant that tells at what value the sine function has when $t=0$ and $x=0$. If one happens to have two waves ovelapping, then the $\phi_1$-$\phi_2$ of the functions is the phase difference of the two waves. How much they differ at the beginning ($x=0$ and $t=0$), and this phase difference is evidently kept all the way through. share | cite | improve this answer.
