Is there any word or combination of two words that describes two persons with the same characteristics.
If you're open to idioms, you could say that these people are cut from the same cloth.
Of the same nature; similar:
don’t assume all women are cut from the same cloth
Or they're like (two) peas in a pod
So similar as to be indistinguishable or nearly so:
they were like two peas in a pod, both with the same high cheekbones and hairline
You could use similar or analogous.
(Of two or more subjects) similar to each other
The brothers were very much alike
