6. (Problem 1) Which of the following describes a quantitative characteristic? A. Always dominant B. Always recessive C. Has a continuous variation in phenotype D. Has a few discrete phenotypes E. Never influenced by the environment 1. A Mendelian population is one that: A. is a group of interbreeding members of a species. B. evolves through changes in its gene pool. C. meets Hardy-Weinberg equilibrium conditions. D. A and B. E. All of the above. 24 As population genetics is studied, all of the following are of interest EXCEPT: A. genotype frequencies. B. allele frequencies. C. phenotype frequencies. D. mutation rates. E. Actually, all of these are of interest. 3. Blue eyes are recessive to brown eyes in humans. If the frequency of blue-eyed individuals in a population is 16%, we can calculate that the frequency of the allele for blue eyes is: A. 16%. B. 32%. CC. 40%. D. 48%. E. None of the above. 4. The Hardy-Weinberg equilibrium requires all of the following assumptions EXCEPT: A. mating is random. B. the population is small. C. no selection is taking place. D. there is no immigration or emigration. E. Actually, it requires all of these assumptions.
