D. bottleneck events
Bottleneck events occur when a population undergoes a dramatic decrease in size, often due to natural disasters, habitat destruction, or other factors. This reduction in population size can lead to a loss of genetic diversity as certain traits may become more prevalent while others may be lost entirely. Inbreeding can also become more common in small populations, further limiting the gene pool. Overall, small populations are more vulnerable to losing genetic diversity, which can impact their long-term survival and adaptability.
Why are the gene pools of small populations reduced compared to those of larger populations?
A. lack of advantageous traits
B. inbreeding
C. lack of suitable mates
D. bottleneck events
