This climate made the region have insufficient water to sustain a lot of people and make it really hard for many agricultural crops to grow.

Answer: The Allele frequencies in the fish population will become more similar over time.
Explanation: The Allele frequency also known as the gene frequency, is the relative frequency of an allele (which is a variant of a gene) at a particular section in a population, normally expressed as a fraction or percentage.
To be more precise , it is the fraction of all chromosomes in the population that carry that gene.
If during a flood event a permanent stream forms between two lakes allowing fishes to move back and forth, it would cause the allele frequencies in the fish population to become more similar.
Case study seeks to understand the particular case because it represents an unusual situation or events or peoples who have rare psychologically abilities and disorders. It is an small scale representation of large fact.
Explanation:
Case studies refers to small scale spatial analysis of a particular event. In research methodology it is a well known methodology. Ina vast research area for depicting some sorts of result in concrete way case studies are taken frequently. For e.g. someone is studying arsenic contamination in ground water at West Bengal. Now this is a large and macro scale study.
For analyzing or applying all the techniques to perfectly measure the result one has to do micro level study. For that reason we can take a case study of a community development block. It will be more authentic and practical then.
