Question

Which conditions are common to all three of the following: genetic drift, the founder principle, and the bottleneck effect? a. in small populations when one genetic trait becomes more common in a population purely by chance b. in small populations and result in a decrease in genetic diversity and/or an increase in the occurrence of specific genetic traits c. when a small group of organisms only reproduce with each other to create a larger population of organisms d. when the majority of a population is killed off and there are only a few remaining organisms left to rebuild the population

Answer 1

Explanation:

Common to genetic drift, the founder principle, and the bottleneck effect:

b. in small populations and result in a decrease in genetic diversity and/or an increase in the occurrence of specific genetic traits

c. when a small group of organisms only reproduce with each other to create a larger population of organisms

d. when the majority of a population is killed off and there are only a few remaining organisms left to rebuild the population

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species.

• mutations accumulate in a population over time, altering the frequency of alleles or different forms of a gene- this is called genetic drift.
• In the founder effect, the separation of a group from a larger group can decrease genetic diversity, this can create a genetically distinct population
• In the bottleneck effect, a population die off or barrier to reproduction increases the genetic drift in the population
