Name 1 condition required to maintain genetic equilibrium under the Hardy-Weinberg Principle. Traits that show stabalizing distribution and are determined by more than one gene are called. Breeding cows that give the most milk or the fastest horses is an example of. Darwin's idea that each living species has descended with changes from other species over time is called. Lamark proposed that organisms could alter the size or shape of their bodies through use or disuse and pass these traits on to their offspring. In addition to observing living organims, Darwin studied the preserved remains of ancient organisms called. Name the island where Darwin observed finches, iguanas, and turtles that led to his Theory of Evolution. A well supported testable explanation of phenomena that have occurred in the natural world is called a. The process in which organisms that are better suited to their environment survive and reproduce is called. Which of the following is NOT part of Darwin's theory of evolution? Organisms in a population show a natural variation in heritable traits. Organisms must compete for resources because organisms produce more offspring than can survive.

Identify the letter of the choice that best completes the statement or answers the question. The gradual model of evolutionary change proposes that most morphological change occurs. If the frequency of a recessive gene in a population under genetic equilibrium is 40 percent, in the next generation the frequency of that gene would be. If the frequency of the recessive allele is 30 percent, the frequency of the heterozygous carrier would be what percent? Suppose that you have a population of guinea pigs in which two-thirds of the alleles for coat color specify black and one-third specify white. According to the Hardy-Weinberg rule, what will be the ratio of these alleles in the gene pool in future generations, provided all the guinea pigs reproduce? Four of the five answers below are consistent with Darwin's theory of natural selection. Select the exception. All populations tend to overproduce. Some members are more adapted to the rigors of competition. Limited resources put limits on population growth. Variation in individuals is not inheritable. Traits appear and disappear.

C are reproductively isolated from other like groups.

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. If the 2nd donor has a million set of genes, the recesive ones, then there might merely be a million set of genes. Answer Save. Favorite Answer. E 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. D Microevolution is the change in a gene pool of a population, where as macroevolution is the change in MANY gene pools. Hope I've been helpful. Those are just the correct answers.
