Do you select against specific traits when looking for a mate?

I can’t avoid thinking like this. Biology is in my blood. It doesn’t even matter that I am not planning to have a kid for almost a decade.
I know that I am a carrier for colorblindness, and therefore avoid colorblind men. That is the only time when it is possible to have a colorblind girl, with the crossing of a carrier and an individual with colorblindness.
I always attempt to select for diverse genetics and preferentially opt for heritage other than my own.
I try and select for good metabolism because I am not blessed with one.
And so on and so forth. Make Note: These aren’t traits that I find sexually attractive and are instead criteria for mates with the intent of protecting future offspring.
Anything that narrows down the possibilities is nice, too.

Do you have anything you select against because of genetics? Do you keep in mind what you’re a carrier for when dating? Do you even know what you’re a carrier for?
