1. Identical twins had different eating habits. Consequently, Twin A had an excessive amount of stored fat tissue that affected gene regulation, resulting in insulin resistance. Twin B did not have insulin resistance. Which statement based on this situation is correct?
A mutation on the operator region of the insulin gene most likely formed in Twin A.
There was variation in the DNA code for the insulin gene between the twins.
Gene regulation is independent of genetic similarities in organisms.
The phenotype of genetically similar organisms can differ due to gene
