It was a team of scientist that first reported CFTR gene mutation in children with Cystic Fibrosis. The team worked in North-East of Iran.
It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.
In 2003, a group of researchers reported on a new genetic mutation associated with primary amenorrhea.
There is no such thing as "the first duck." all things on earth evolved slowly, mutation by mutation, so that they fit their environment. Things that have good mutations live and have kids, and their kids have that mutation. That's how evolution works.
First case of PKU was reported in Munster Germany in 1964.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It was first reported as a separate pathologic entity by Gorlin et al in 1962
It is believed to have been a mutation of a dinosaur.
The permanent change in a gene or a chromosome is called Mutation.
