Explanation

A lethal mutation refers to any and all mutations that prevent an organism from reproducing in any way. Lethal mutations do not have to kill the organism to classify as lethal. An example of a lethal mutation in humans is Turner syndrome which is a disorder whereby the 23rd chromosome pair only contains an X chromosome. The person lives but is infertile. Turner syndrome is caused by a missing or incomplete X chromosome. People who have Turner syndrome develop as females.
