In contrast, mutation of one copy of the operator confers a mutant phenotype because it is dominant to the second, wild type copy.

However, cross resistance where mutations confer resistance to two or more treatments can be problematic.

These mutations confer the bacteria emergence of antibiotic resistance.

It has been hypothesized that mutations in the CFTR gene may confer a selective advantage to heterozygous individuals.

Other mutations confer lower risk, but are more prevalent in the population.

Rene, some of the factors have been identified, e.g. mutations in the gene CCR5 confer resistance to HIV.

These mutations would often confer superpowers as well as physical deformities, but the powers granted would never be the equal of those wielded by Eternals.

Other mutations including insertions and deletions in the background of the above mutations also confer resistance via enhanced excision.

Thus, the secondary more dominant CSCs may emerge, if a mutation confers more aggressive properties (Fig. 5).

Some random (and compounded) mutations will confer much greater benefits than others.
