You are a biologist interested in the variation in the body size of Florida sea turtles. You know that body size is determined by a single locus with two alleles, with large body size (A) dominant over small body size (a). You survey the body size of 100 turtles and observed the following phenotype frequencies:
• Large bodied turtles (AA and Aa) = 84
• Small bodied turtles (aa) = 16
If the population is in HWE, how many turtles of each genotype would you expect?
a) AA = 42, Aa = 42, and aa = 16
b) AA = 36, Aa = 48, and aa = 16
c) AA = 84, Aa = 0, and aa = 16
d) AA = 24, Aa = 60, and aa = 16
e) AA = 16, Aa = 68, and aa = 16
Rank these processes with respect to their rate of evolution (from fastest to slowest).
a) Pseudogenes, synonymous substitutions, nonsynonymous substitutions
b) Pseudogenes, nonsynonymous substitutions, synonymous substitutions
c) Nonsynonymous substitutions, synonymous substitutions, pseudogenes
d) Synonymous substitutions, pseudogenes, nonsynonymous substitutions
e) Synonymous substitutions, nonsynonymous substitutions, pseudogenes
