When a new population starts from a few organisms and their traits become common in the whole population this can be linked to what?
Answer and explanation
Correct answer: Founder effect
The founder effect is a special case of genetic drift. When a new population is established by only a few individuals, the allele frequencies of those founders may differ from those of the original population. Their inherited traits can therefore become unusually common in the new group, purely because of its small starting sample. Option A is correct; the other choices concern nutrition, comparative anatomy, or iodine deficiency rather than population genetics.
