or something like that.

so females have fertility. why not males Virility? I mean if you have a male cub born from a super VLF female, and he doesn't have a mute, what's the point?

What if males can now help contribute, even if only a small bit, towards the cubs' likelihood of more common mutations, with a much more slim chance of uncommon/rare mutations?

Of course, it will not make it any easier for mutations. In fact, a low verility male would likely have a much harder time GETTING a female pregnant if she too has low fertility.

I'm sure this won't get many supports, and I'm still fleshing everything out.

But they'd have similar levels, but be less likely to pass on mutations but when paired with a VLF female and a VLV male, would be a bit more likely to pass on more uncommon/rare mutations.
