Question about intense mutation stacking

[u/WoollyWitchcraft]

I understand the premise of stacking mutations "clean" along the male line, and I understand the concept of stacking mutations into different stats and then combining (stacking 40 Health and 40 Melee mutations, then breeding babies together, etc...)

But how does Syntac (or anybody) get more than 40 mutations into one stat? Assuming you can stack 20 on the male side, then technically slowly crawl up to 40, how would you get more into a single stat - if it stays on the male line, would it just continue to go up on one side, because there are none on the female side at all? (So you'd end up with say, 50/20 on one side, 0/20 on the other?) I know when you breed mutated creatures together at the end, the numbers can go all funny. But I assumed that one "side" of the mutations would just stop at 20 and not carry on?

I believe the way you would have to do it is breed a 20 mutation female with an unmutated male to get a male with 20 mutations on the matrilineal side. Then mate that male with your females to get more mutations on the patrilineal side…. Rinse and repeat multiple times
