The following multiple choice questions are examples of the sorts of questions you should be able to answer. Directions: Answer the following multiple choice questions by choosing the letter of the response that represents the best answer to the question. Which of the following is not a source of variation in a population? Inherited genetic differences. Differences due to health. Differences due to age. Differences due to accident. None of the above. Which of the following examples of variation is not important from an evolutionary standpoint? Genetic differences between individual organisms comprising the population. Inherited differences between individual organisms comprising the population. Differences due to diet, health, age or accident that have no affect on an individual's ability to survive and reproduce. A and B. Why is genetic variation important from an evolutionary standpoint? If all organisms were the same, the entire population would be vulnerable to particular pathogens, like viruses. All evolutionary adaptations e. Evolution at the population level refers to changes in the frequencies of genes in the population over time. All of the above. Which of the following is an example of genetic variation? Two children have different eye colors. One person is older than another. One person has a scar, but her friend does not. Todd eats meat, but his brother Rod is a vegetarian. Which of the following is an example of environmental variation? Apu is a tongue roller, but his brother Sanjay is not. Marge dies her hair blue. Homer inherited baldness from his father's side of the family. Patti and Selma have hanging ear lobes. Bart is a boy because he has both an X and a Y chromosome. What's the difference between natural selection and sexual selection? Sexual selection occurs during sex.

For the percentage of the population able to break down lactose in adulthood, what is the genetic cause of this ability? Differences in skin color, the ability to metabolize alcohol, and cholesterol levels are just a few examples of:. Darwin found that the rain forest species in South America were more similar to which other species? The fact that during Darwin's lifetime he changed his mind with regards to species changing over time illustrates which important fact about scientific inquiry?
The closer two species are the more similar their DNA is because their gene pools have not be separated long enough to allow for big genetic changes to take place. Its not "a" because convergent evolution is when two different species evolve to look similar because they live in similar habitats, which has nothing to do with this question. It is not "b" because microevolution is the change in a gene pool, which also has nothing to do with this question. It is not "c" because no where does this problem ask for artificial selection. And it is not "d" because fossil record completion does not have anything to do with two species being related. Microevolution is the change in a gene pool of a population, where as macroevolution is the change in MANY gene pools. Since this question is only talking about ONE species i would assume it is microevolution. You can cross out "a", "b" and "e" immediately because they have nothing to do with this problem. It is between macro and microevolution and in this case micro makes more sense to me. DNA is the genetic material that determines all our inherited characteristics. So, the more closely related two species are the more similar their ancestry, or inheritancethe more similar their DNA will be. Microevolution is the term used to describe evolutionary changes within a species - eg the changes in camouflage observed in the peppered moth during the Industrial Revolution in England. Macroevolution which probably starts out as a series of microevolutionary changes describes how evolution can give rise to completely new species over time. The first four answers on the first question really have nothing to do with the question and are just false. Irreducible complexity is a proposition from intelligent design, and both of them are quite irrelevant in this question. Macroevolution is evolution on a much, much bigger scale than microevolution. Interspeciary changes are results of microevolution. If i'm information the words wisely, the ideal answer may be B. Heterozygous skill a million set of dna donors? And recessive might recommend that donor has a million set of dominant genes and a million set of recessive genes, that's the only assumption i will make because of the fact there isnt adequate information asserting no remember if or no longer the 2nd donor shows the recesive features. So if the 2nd donor has 2 contraptions of genes, that would recommend there may be 2 contraptions of genes entire.
