ASU BIO 345 Exam 1 Questions and Answers 100% Pass evolution - change in allele frequency over time Feather color in male lazuli buntings, a bird species native to North America, is under selection. The feather brightness of males varies, ranging from brown to bright blue. In a habitat with limited nesting sites, both the dullest and the brightest yearling males are more successful in obtaining high quality territories and therefore attract females. This is because adult males tolerate n...

Binghamton Bio 114 Exam 2 Questions and Answers Already Passed Genetic Drift Refers to the ongoing variation in allele frequencies within a population over time due to random mating events. Genetic drift causes allele frequencies to fluctuate randomly. Random Mating Influences allele frequencies by altering how often specific alleles appear within a population. This process is inherently unpredictable, with allele frequencies increasing or decreasing randomly. Bottlenecks O...
