Rules:
- Normal Sudoku rules apply.
- Modular lines (turquoise) : every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {3,6,9}, one from {1,4,7} and one from {2,5,8}.
- Genetics lines (grey): each "child" cell connected to two "parent" cells in the row above must have the same parity as one parent and the same modularity as the other parent.
- Digits along lines may repeat if allowed by other rules.
- Digits joined by a black dot are in the 1:2 ratio.
- Digits joined by a white dot are consecutive.
- Not all dots are given.

really fun rule set. It's great that it's different enough to be new, but close enough to other line logic that it's not too hard to work with out of the gate

Awesome deductions in this one! Box 1 had me struggling for a while, I'm glad I kept at it!
