1.   This will tend to apply to all the logs placed by any beaver bearing this particular mutation.

2.   In the previous chapter we saw, on purely statistical grounds, that any particular large mutation is inherently less probable than any particular small mutation.

3.   Almost no blacks have the particular protective mutation investigated in this study, but scientists say other forms of genetic immunity almost certainly exist in both blacks and whites.

4.   But doctors cannot always tell how dangerous a particular mutation is.

5.   Hence the prevalence of these particular mutations in certain peoples.

6.   One reason this might happen would be if this particular mutation has a tendency to occur spontaneously.

7.   The new research simply identified a particular genetic mutation, that is more common among deaf Jewish people than among deaf people from other backgrounds.

8.   They found the location by examining the genetic material of a large Mexican family, whose members may be the only humans known to have this particular mutation.
