Question

10. In the late 1960s and early 1970s the neutral theory of molecular
evolution was proposed and elaborated. This plot compares the
numbers of nucleotide substitutions for two types of mutations. The
higher rate of substitution for synonymous mutations is consistent with

c. Lamarckian evolution.
d. the neutral theory. c. the theory of heterozygote excess.


7. The Hardy-Weinberg Equilibrium Law assumes (a) an infinite size
population, (b) no mutation or migration, (c) no selection and (d)
random mating. Under these conditions even populations not in
equilibrium will a. attain equilibrium in a generation and stay in equilibrium forever.
b. achieve mutation-selection equilibrium in one generation. c.drift from one allele
frequency to another. d. show remarkable increases in genetic variability.
e. attain equilibrium in n-q generations.
