When the population of twenty blue grasshoppers arrived on that new island (called Greenland), they joined thepopulation of green grasshoppers already living there. The newly arrived grasshoppers have an exoskeleton that is blue incolor. The introduction of the rare allele for blue exoskeleton color into the population of green grasshoppers is anexample of what type of microevolutionary process?AFounder EffectBottleneck EffectMutationNatural Selection The next five questions (questions 11-15) are related to each other. Read all of the scenarios very carefully and in orderand select the correct answer.A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grassesbecause they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, ashort-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out thegrasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is anexample ofGene FlowFounder EffectC Natural SelectionGenetic Drift

Introduction loss of genetic variation occurs in founder effect. solution 1.founder effect is the correct answer. The founder effect is that the reduction in genetic variation that results when alittle subset of an outsized population is employed to determine a replacement colony. The new population could also be very different from the first population, both in terms of its genotypes and phenotypes. 2 genetic drift is correct answer. Genetic drift describes random fluctuations within the numbers of gene variants during a population. Genetic drift takes place when the occurrence of variant sorts of a gene, called alleles, increases and reduces accidentally over time. These variations within the presence of alleles are measured as changes in allele frequencies.
