Final answer:
Realism was greatly influenced by the genres of Local Color and Regionalism, which focused on detailed and accurate depictions of ordinary people and their lives.
Step-by-step explanation:
The genre that greatly influenced Realism was Local Color along with Regionalism. They both contributed to the emergence of Realism by focusing on accurate details and the representation of ordinary people and their dialects, characteristics, and social classes. While Regionalism and Local Color often dealt with specific geographical areas and the unique aspects of its inhabitants, Realism expanded upon this by developing more complex characters and focusing on contemporary life issues. It strove for truth in storytelling through attention to detail without the artificiality of heroic or sentimental treatments seen in previous literature styles like Romanticism.
Thus, Realism moved beyond the limitations of Local Color and Regionalism by depicting life as it was, with an emphasis on middle-class experiences and the struggles of everyday people, often including the darker aspects of life in stories with unresolved conflicts.
