They will have different sex chromosomes (Y from tiger or lion) and different mtdna. So there might be some slight differences. And it's not out of the question that one is more viable than the other.

You are trying to take an interesting discussion about species off on a wildly irrelevant tangent. There is no sexism here and the names are not designed to promote patriarchy.
It's off topic and inflammatory. And this follow up comment reinforces the appearance that the point is basically shit stirring and nothing else.
I talk about sexism pretty regularly on HN. Sometimes it doesn't go well and sometimes it does. You absolutely can discuss sexism here. This is just not a good approach to doing so.
