No, humans are not 99 percent banana.
While it's a popular science myth, the idea that humans are 99% banana is incorrect. While humans and bananas do share some genetic material, particularly regarding protein-making genes, the overlap is limited and doesn't equate to being "99% banana". According to the reference, we share 40% of our protein-making genes with bananas. However, these protein genes only account for about 1% of human DNA. The remaining 99% is a critical difference.
