Question

"The best explanation for these modified rice plants being flood resistant is that

(1)the gene for flood resistance was inserted into plant cells, which grew into plants whose cells are expressing this gene
(2)they were produced by fertilization, using gametes from two flood-resistant bacterial cells
(3)there was a mutation in the bacterial DNA after it was inserted into the plant that caused it to be flood resistant
(4)the researchers used selective breeding for the flood-resistance trait"

Answer 1

I would rather suggest.....4th one as researcher mad hybrid that is flood resistance by selective breeding !!!
