Question

Quizplus · Accepted Answer

The given scenario where only a few individuals survive unfavorable times and lose the majority of genotypes in the next generation is indicative of the bottleneck effect. This is a genetic phenomenon where a significant proportion of the population is lost in random events such as natural disasters, diseases, or human activities. This leads to a reduction in genetic diversity because the surviving individuals carry only a subset of the original genetic variations, leaving some alleles entirely lost. The reduced genetic diversity can make the population susceptible to genetic disorders or unable to adapt to changing environmental conditions.
