Question
Population Genetics xperiment 2: Genetic Drift enetic drift, the variation in the gene pool and/or gene frequency of a opulation, can result from a variety of stochastic (random) events. Consider the ollowing population of butterflies that has half of its habitat destroyed by wildfire Figure 3) FIRE Figure 3: Butterfly populations before and after wildfire. The remaining population has 50% of the initial gene pool (two colors), and the gene frequency is different. As these individuals reproduce, their offspring will no longer reflect the original population.Explanation / Answer
1. On observing the surviving population, it contains individuals of the same species and also combination of genes in the population. That is different forms of the same group ( yellow and green butterflies) presented in the different combinations which represent the gene frequency of the population.
2. After fire, the population of butterflies has been reduced to half of the one presented in the breaker 1 when compared with beaker 2. Combination of types of butterflies reduced were in equal amounts.
3. In the gene pool represented above, different types of allels were presented among the existing population. Genetic variation can be caused by different factors and here the factor will be fire. This caused different types of allels of butterflies to be presented in surviving population.
