Answer 1

All of the given options contribute to the reduction of gene pools in small populations. Inbreeding can lead to a decrease in genetic diversity and an increase in the frequency of harmful genetic traits. Lack of advantageous traits means that there is a limited range of beneficial genetic variations in the population. Bottleneck events occur when a large portion of a population is destroyed, leading to a decrease in genetic diversity. Lack of suitable mates can lead to reduced opportunities for breeding and genetic variation.
