We are still in the process of understanding why some mutations actually increase abilities yet take others away.

Some mutations increase resistance to the drugs to a large extent than others.

Mutations in the genes increase risk of breast cancer even more.

The mutations also increase a woman's risk of ovarian cancer.

The per mutation significantly increases the percentage of abnormally located cells to about 40%.

However, this mutation also increases the prevalence of coronary heart disease in patients with hypertriglyceridemia.

"This mutation may just increase the susceptibility to seizures."

Recurrent mutation can increase the frequency of a mutant allele.

Mutations in the Shine-Dalgarno sequence can reduce or increase translation.

After only a few generations, the mutations that enhance rapid reproduction or dispersal will increase in frequency.
