Thanks for putting that in quotes.
Genetic Drift is a population biology concept.
Stochastic changes in allele frequency NOT due to selection.
except in cannabis…where apparently folks apply that to what I would call “Clonal Fading”.
As Dr Brunstein states, genetic drift is NOT the correct term.
What is Genetic Drift?
Now we’re ready to define what genetic drift actually means. It is a change in the allele frequencies at a locus in a population. If you have a single plant – or even if you have a group of genetically clonal plants such as from cuttings – that’s not a population in the genetic sense of the word, there’s only (at most) two alleles for each locus, and there’s no change over time in the relative frequency of each allele – it’s either 100 percent or 50 percent.
The words “genetic drift” can only be applied to heterogenous populations of a species over normal reproductive cycles – for any of you looking for more reading, it also only occurs when said population is not in Hardy-Weinberg equilibrium, which is a fancy way of saying some form of non-random mating or selective pressure is occurring to alter allelic frequencies over reproductive generations. If all of that lost you, the bottom line is genetic drift, by definition, doesn’t occur in a single individual organism.
