option (2) help in eliminating the non tranformants, so that the transformants can be regenerated.
This is because Selectable markers help in identification and elimination of non-transformants while permitting selective growth of transformants.
A selectable marker is used to : (1) Mark a gene on a chromosome for isolation using restriction enzyme (2) Help in eliminating the non-transformants, so that the transformants can be regenerated (3) Identify the gene for a desired trait in an alien organism (4) Select a suitable vector for transformation in a specific crop
