Probably not. As in: most of our DNA is (near) identical but our phenotypic traits are determined by more than just the DNA. In a DNA test we don't look at the identical bits, we pinpoint for the more variable regions and repititions.

A funfact, there are animals that look very similar but are genetically extremely far apart. Different genes can result in similar traits in a completely different way. I can't remember the example my prof used in college but it was super interesting.

Could you be remembering convergent evolution and analogous structures? It’s when two unrelated animals have similar ecological niches, so they end up adapting to it in similar ways. Like sharks and dolphins both having similar shapes and dorsal fins to swim in water, or echidnas and hedgehogs both having prickly spines.

Maybe colugos who look like fruit bats. The former are primates and the latter are just bats.
