Point Mutation
... Hutchinson-Gilford progeria syndrome The disease is caused by a small point mutation on a single gene known as LMNA. Almost all cases are caused by the substitution of only one base pair out of the approximate 25 000 DNA base pairs that compose the LMNA gene. This gene codes for the protein lamin A ...

... Therefore, if a trait is found only on the X it will be expressed in a male regardless of whether it is dominant or recessive. X – inactivation occurs in females. Every normal woman has two Xs but they only need one. Therefore, one X chromosome turns off, forming a Barr body. Because X – inactiv ...
