Historically, the population of california condors probably numbered in the thousands of birds. however, because of human use of
pesticides, hunting, and habitat destruction, the population declined to no more than 13 individuals. now, thanks to captive breeding, reintroduction programs, pesticide control, and habitat preservation, the population is increasing in size. what would you predict would be the primary difference in numbers of alleles per locus and allelic frequencies in the prehistoric versus modern (recovered) populations of condors?
<span>The California condors have survived genetic bottleneck which is the huge reduction in the size of a population<span> due to environmental events or human activities. Because t</span>he genetic bottleneck resulted in inbreeding and decreased fitness, the<span> genetic diversity of California condors increased dramatically. Besides the evidence that the bottleneck led to the loss of genetic variation and changes in allele frequencies, it has been shown by recent studies that there was an increase in the frequency of the putative allele for chondrodystrophy, which is a lethal form of dwarfism.</span></span>
With a certain species out of the food chain this leaves other animals population to dwindle because of them feeding off of the migrating animals. Meanwhile other plants and animals might flourish because these animals would no longer be a threat to their species.
