Why are the gene pools of small populations reduced compared to those of larger populations?

1.lack of suitable mates
2.lack of advantageous traits
3.bottleneck events
4.inbreeding..

5. Greater vulnerability to genetic drift

6. Higher likelihood of harmful recessive alleles being expressed
7. Decreased overall genetic diversity

Yes, the reduction of gene pool in small populations can be attributed to lack of suitable mates, lack of advantageous traits, and bottleneck events. These factors can lead to a decrease in genetic variation and increase the risk of inbreeding, ultimately reducing the overall health and adaptability of the population.
