'Mutation rates' diaporamas de présentation

When Darwin wrote the Origin , he imagined that . . .

The capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music. Lewis Thomas, 1979 The Medusa and the Snail. When Darwin wrote the Origin , he imagined that . . .

Mutation can change population genetic structure

Mutation can change population genetic structure. Mutation rates are low typically <1/10,000 per generation ( ? ? 0.0001) Loss-of-function mutations are much more common than back mutations that restore function. WHY?. How does selection cause change in allele frequencies?.
