1 Dagobert II, 679; he was one of the last kings of the Merovingian line, murdered by persons unknown in the Ardennes Forest on December 23.  Giovanni Borgia, 2nd Duke of Gandia, 1497; his body was recovered in the Tiber with his throat slit and about nine stab wounds on his torso.
Bottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.ottlenecks and Founder Effects.

Best Answer: 1. Genetic Drift: This represents random changes in small gene pools due to sampling errors in propagation of alleles. The bottleneck effect and founder effect are prime examples of genetic drift.In either case the number of individuals in a population is drastically reduced distorting the original allelic frequencies. 2. Gene Flow: The movement of alleles into and out of a gene pool.Migration of an organism into different areas can cause the allelic frequencies of that population to increase.he bottleneck effect and founder effect are prime examples of genetic drift. In either case the number of individuals in a population is drastically reduced distorting the original allelic frequencies.
