I got pretty angry because i studied every part of genetics including the last bit with gene cascade etc and they werent tested I was also abit confused about the linked genes one. Isn't a linked gene result suppsoed to be 3:1? I got 1:2:1

Same... but even though I studied it, I'm still glad there was nothing from part 8. It sucks

With linked genes, if it is a case of the DOMINANT alleles (A and B) on the same chromosome, ie. linked, then the ratio is 3:1. This question had A and b on one chromosome and a and B on another. You see? That's why it gave a different ratio.

Yes, the 1:2:1 ratio is correct.
