BIO 112 ASU Final Exam Questions and Answers Already Passed Natural selection: Basic requirement for natural selection to occur in a population: organisms in the same population must differ from one another in their heritable traits. Examples of natural selection and evolution at work include which of the following? -The case of the bacteria Staphylococcus aureus resistance to first penicillin, then methicillin, and now vancomycin. -Housefly resistance to DDT within a decade of its ...

Natural Selection the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic controlled by more than one pair of alleles located at different gene loci Directional Selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection Occurs when an intermediate phenotype is favored. Individuals near the average are fav...

BIS 2B Final Exam (Part I) With 100% Correct Answers 2023 Community - set of species in a particular place Ecosystem - all species and their abiotic environment in a place Biological evolution - change in the properties of populations over the course of generations caused by descent with modification Natural selection - process that produces adaptations from differential reproductive success among organisms in same populations Stabilizing selection - favors and...

Intersexual Selection - this is where members of one sex evolve preferences for specific qualities in potential mates. This causes the members of the opposite sex who have these qualities to have an advantage and more of a choice of who they want to mate with Outline the rationale behind sexual selection including long term mate preferences - ANSWER-Although on the face of it being choosy about mates wastes time and energy in the long run it is essential. The rationale behind it is that if yo...

What is relative fitness? correct answers the survival and/or reproductive rate of a genotype (or phenotype) relative to the maximum survival and/or reproductive rate of other genotypes in the population.
