Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
Answer:the most basic of your trait and heridty
Explanation:
One example of irradiation solving a societal problem might be the way
in which it is able to prevent diseases in food. Using small amount of
radiation, the bacteria and insects that would otherwise be carrying
harmful bacteria can be killed. This will solve a societal problem, in
that food wastage and illness due to food poisoning in poverty-stricken
areas are massive problems faced in our society.
