| The improvement in height was attributed in part to natural and artifical selection for rapid growth, but primarily to a reduction in inbreeding. |
| The interaction of natural and artifical selection continues to be one of the least studied aspects of quantitative genetics, both theoretically and experimentally. |
| An artifical skin comprising an insoluble atelocollagen sheet and an epidermal cell layer cultured on one surface of said sheet. |
| Darwin contrasted natural selection with the artifical selection by people of plants and animals. |
| These catchment areas are artifical basins which collect rainwater during the wet season and store it for use during the hot and dry season. |
| Seed irradiation has already been shown to be effective for inducing new genetic variability useful for artifical selection. |
