This could happen by genetic drift if the population is small enough.
Genetic drift is the name given to this loss of variation.
The strength of genetic drift depends on the population size.
Most are caused by a random process known as genetic drift and have little effect.
The point is, you don't get that high numbers by genetic drift alone.
Clearly we're talking about quite a large ship, with a population in the hundreds at least: high enough to prevent genetic drift.
Through genetic drift, such traits may become less common or disappear.
One such is the role of genetic drift in speciation.
His claim may be authentic given the principle of genetic drift.
The random spread of genes is known as genetic drift.
