Lac Operon 7 For the following genotypes indicate whether beta-galactosidase and permease are produced under the listed environmental conditions. Use the following categories: High: if the normal gene product is produced at a high level Basal: if the normal gene product is produced at a basal level Lower than basal: if the normal gene product is produced at levels lower than basal (even extremely low), but higher than no product None: if the normal gene product is not produced, or is produced at an extremely low level.
