A single gene causes pistol shrimp to have eye
pockets. Some pistol shrimp lack the allele for eye
pockets. What result will natural selection most
likely cause on the population of pistol shrimp?
A The allele for eye pockets will become less
common in the gene pool because they are
harmful to the shrimp.
B The allele for eye pockets will cause the
shrimp to go extinct because eye pockets
take too much energy to produce.
