- Q1Which evolutionary process describes the loss of genetic variation that occurs when a population is drastically reduced in size?stabilising selectiondirectional selectionfounder effectgenetic bottleneck30s
- Q2What is the term for the phenomenon where a small group of individuals establishes a new population, leading to reduced genetic diversity?founder effectgenetic bottleneckgenetic driftstabilising selection30s
- Q3Which type of selection favors intermediate phenotypes over extreme ones?founder effectdirectional selectiongenetic driftstabilising selection30s
- Q4Which evolutionary mechanism is characterized by random changes in allele frequencies within a population, particularly in small populations?directional selectiongenetic bottleneckstabilising selectiongenetic drift30s
- Q5Which process occurs when environmental pressures favor one extreme phenotype over others in a population?genetic bottleneckgenetic driftdirectional selectionstabilising selection30s
- Q6What term describes a situation where a population experiences a sharp reduction in size, resulting in a decrease in genetic diversity?genetic bottleneckdirectional selectionstabilising selectionfounder effect30s
- Q7What is the result of directional selection in a population over time?the population becomes extinctgenetic diversity remains unchangedthe frequency of a specific phenotype increasesall phenotypes are equally favored30s
- Q8Which evolutionary concept involves a significant reduction in population size followed by recovery, affecting the genetic variation within that population?genetic driftfounder effectgenetic bottleneckdirectional selection30s
- Q9Which process leads to decreased genetic variation as a small group establishes a new population distinct from a larger one?founder effectstabilising selectiongenetic bottleneckdirectional selection30s
