Do brothers that look alike but are 9 years apart of age share the same genes?

Not the exact same genes but their DNA would reveal the sibling relationship.

All biological brothers share some of the same genes, no matter how they look.

Brothers with the same parents share about half their genes regardless of whether they look alike or not. Its just chance how much they look alike but its still about 50% of their genes.
