Actually, on second thoughts maybe I could be wrong. Perhaps it is possible for two cousins to both inherit (and therefore share) specific genes that could make them more closely related than two half siblings who inherit different genes from the shared parent.

Yeah, the cousins do not actually have to be more related, but i'm thinking if half siblings and cousins are somewhat equally genetically related. Like Y chromosome wise, it wouldn't be possible to tell two cousins whose fathers are brothers apart from siblings who only share the same father. Or what?
For siblings, they are roughly 50% related to one another, but this is just an estimate.
Thats what I meant, its just an estimate since siblings can have more or less genes in common whereas the secure relation to the parents is minimum 50 percent (if excluding the male-female difference with the y-chromosome).
In a related group, populations, all people are more related than random people from different parts of the world on which such theoretical estimations are rather based.

If ur mom and dad r white. and ur half brother's dad is white, the same as urs, but ur mom is black, and ur cousin is all white. Then ur closer to ur cousin than to ur half-brother.
But it depends on who ur parent marries, and who ur cousin's parent that ur related 2 marries.
I'm guessing it kind of make sense because both your mother and father are probably genetically closer to your cousins parents since they're all of the same race. How related are cousins if their mothers are sisters and their fathers are brothers?
