Question
20. A mutation occurs in one of your lung cells. Which of the following is true? a. you have evolved to be better adapted to your environment b. you will soon die because most mutations are lethal c. you will be sterile and no longer be able to have children d. the human species will have evolved because this mutation will be passed on to your children e. this mutation does not affect the human gene pool because it will not be passed on to offspring 21 The many species of Galapagos finches were each adapted to eating different foods. This is an example of a. Gene flow b Adaptive radiation c. patric speciation d Both a and b are correct e, a, b, and c are all correct 22. A chance event, such as a hurricane, occurred that caused a population to lose many individuals (they died). As a result the population lost alleles because of a. mutation b. migration c. selection genetic drift 23. A human population has a higher-than-usual percentage of individuals with a rare genetic disease. The most likely explanation is: Gene flow g. Stabilizing selection h, Directional selection Genetic drift All of the preceding 24 Which of the following did NOT occur to Darwin on the voyage of the Beagle? a. He read Lyles Principles of Geology b. He observed living animals and similar fossils c. He read Malthus' Essays on Population d. He witnessed an earthquake and the resulting fault e. All of the above DID occur on the voyage.
Explanation / Answer
O1) Answer is e
this mutation does not affect the human gene because it will not be passed on to offspring.
Mutation in somatic cells will not appear in the next generation;
2) Answer is B
Adaptive radiation
It is a process in which organisms diversify from an ancestral species into new forms, when a change in the environment takes place
3) Answer is D
Genetic drift
4) Answer is Genetic. Drift
Genetic drift occurs when allele frequency occurs by chance
