When I applied for grad school, I did not specify genre. I said I wanted an MFA in Creative Writing. I was so cute and stupid! The admissions committee at Pitt decided to put me in poetry.
Given the devaluation of literature and of the study of foreign languages per se in the United States, as well as the preponderance of theory over text in graduate literature studies, creative writing programs keep literature courses populated.
When I taught at the University of Houston in the Creative Writing program, we required the poets to take workshops in fiction writing, and we required the fiction writers to take workshops in poetry.
