I’ve also observed - anecdotally only - that parents tend to fit into different roles regardless of their gender. I’ve seen male-female parents where the woman is the one who does the rough play and is stricter, and the man is more into art and stuff and is an easier ride - definitely not conforming to gender stereotypes but still being of different genders.
Female-female parenting couples, IME, tend to conform to gender stereotypes somewhat, too, just because you tend to get one person who’s more, say, into rough play than the other, and that role gets extended so that they’re also the parent who takes the kid out on a bike for the first time, and so on. It’s not necessarily a ‘butch-femme’ thing, either. (I don’t know any male-male parenting couples personally). It’s just about personality.
Basically, in any parenting couple you tend to get one parent who has certain characteristics and one who has the opposite, even if they started out pretty much equal before they had kids.
In any case, if you want a variety in a kid’s life when it comes to rough play vs. gentle play, caution vs. gung ho attitude, hair care vs. playing with guns, and whatever other gender stereotypes there are, parents will still never be the only gender role models in any child’s life.
I can see a few advantages to biological parenting as opposed to adopted parenting. There are the little things about inherited diseases and tendencies, and, for many people, there is also just an extra connection - though that probably goes more for the grandparents than the parents.
But those advantages really are tiny (when talking about adopting babies or toddlers, at least - adopting older children is different, obviously). It’s like comparing yourself with the most perfect parent in the entire world: you’ll always fail by comparison. With parenting, you can’t realistically aim for the ideal, just the best that you can do. After all, you don’t expect your child to be perfect either - or, at least, you really shouldn’t.
