In Study 1, the most likely reason the marine sticklebacks that were placed in the pond were tagged was to ensure that the:
A. length of each stickleback could be measured.
B. parents could be differentiated from the offspring.
C. number of plates on each stickleback could be counted.
D. offspring collected would be genotyped only once.

A researcher predicted that moving a marine stickleback population to a freshwater environment would result in an increase in the fraction of offspring with the low phenotype. Do the results of Study 1 support this prediction？
A. Yes, because the FCO for the low phenotype was about 0.13 greater in July 2007 than it was in September 2006.
B. Yes, because the FCO for the low phenotype was about 0.18 greater in July 2007 than it was in September 2006.
C. No, because the FCO for the low phenotype was about 0.21 less in July 2007 than it was in September 2006 .
D. No, because the FCO for the low phenotype was about 0.28 less in July 2007 than it was in September 2006.
