LEVEL
POPULATION LEVEL
Selection on the forms of
the plate gene varies
throughout a stickleback
life in fresh waters.
Freshwater
Freshwater fish don't
develop as many plates
Younger fish without the low form
of the gene survive better
June
November
Three regions of a
stickleback chromosome
have been linked to the
loss of lateral plates
and one lateral plate
gene has been
identified.
Older fish with the low form
of the gene survive better
