Genetic drift in mammals

Autores: BACH,JEAN-FRANÇOIS.
Abstract: Genetic drift is the fortuitous occurrence of genetic events that when they become fixed modify the genome of populations. They can take the form of mutations of single nucleotides (SNPs), the insertion or deletion of short sequences (Indels) or the repetitions of short sequences (CNV i.e. copy number variants) or long insertions or deletion (structural modifications). Their frequency is 10-9 to 10-8 depending on the species, or 50 to 100 per birth in humans. The incidence of these de novo mutations is higher when the father is old at conception. It thus appears that genetic drift, which constitutes the initial element of evolution, has a very strong dynamics. Its intervention in the appearance or disappearance of some major phenotypes is...
