Corn seeds with identical genetic information
were planted on two adjacent farms. the corn

large, while the plants on the other farm were
not given fertilizer and did not grow as large.

(2) the corn plants all contained mutated genes
that made them grow
(3) environmental conditions affect gene

(4) the plants on one farm had different genes
from the plants on the other farm
