How do bottleneck events alter genetic variation in a population?

Expert Solution

Bottleneck events reduces the genetic variation. The bottleneck events leads to sharp decrease in population which in turn leads to loss of gene pool of population.it leads to reduced genetic variability.

Also when there is a small population,there is less chance for random mating(random mating is one of the source of genetic variability).it also lead to reduced genetic variability in a population.

Hope you got it.

Study hard,hard work will not disappoint you.

Meiosis Essay Question: Three events in sexual reproduction contribute to genetic variation in a population: independent assortment, crossing over, and random fertilization. Explain how the three processes of sexual reproduction are advantageous to organisms and generate genetic variation within a population. - State which phase of meiosis is occurring during each of the three events. - Also, explain what is happing during these phases that results in the genetic diversity of offspring. - How is this advantageous to the population...

Describe the four evolutionary mechanisms that alter the frequencies of existing genetic variation in natural populations. You need to define each mechanism and describe at least one example of its action in natural populations (e.g., genetic drift in overhunted populations resulting in less genetic diversity).

Meiosis is an important source of genetic variation in sexually reproducing organisms. Identify the events in meiosis that result in segregation and independent assortment and how these two mechanisms produce genetic variation in the next generation. Use the following terms in your response: genes; alleles; homologous chromosomes; non-homologous chromosomes.
