Punnett squares, pedigrees and the cross the question is hiding
A genetics problem set is logic in a biology costume. The answer is worth one mark and the cross is worth the rest, so the help you want is the working, checked step by step.
Why the mainstream APIs fail here
A model that answers with the phenotype ratio and no working has not helped; you cannot check it and you cannot reuse the method on question six. And when the set touches inherited disease, some models start managing the emotional framing instead of doing the cross.
How MagmaRouter is used for this
Send the cross, ask for the working, then ask what assumption the question was hiding. Paste the whole problem set; context is cheap here. Ask it to generate three more crosses of the same shape for practice, with answers kept separate.
A working loop
- Ask for the cross first and the ratio last.
- Ask which single change to the question would flip the answer; that is the examiner's favourite move.
- Generate practice variants and do them closed-book.
