Which population shows genetic drift?
| Wolves in an island population have redder fur than mainland wolves due to the genetic makeup of the first wolf colonizers. |
| A chickadee population moves to an area that has more seed-bearing plants. |
| A population of tansy begins to bloom later in fall as the climate changes. |
