wasn't it hetro homo hetro, as otherwise there would be no white flower produced due to the purple allele being dominant. that's why the first one would be hetro so it is a carrier of the recessive( white flower) allele
I'm pretty sure it was homo homo hetero as In the first generation all the flowers were purple, meaning that the original purple was homo, and the white was recessive so it had to be homo as well. And as they were both homo, the next generation must be all hetero as they inherited different alleles from each type of flower

Probably an A overall, the B and the A* would round up to an A, and the A in B1 would give it an A overall

I wrote about transect lines with quadrats at regular intervals, but then I crossed out the quadrat part and put a note at the bottom asking the person who marks my paper to mark what I crossed out if it's right (It was still readable, I only put one line through it :P)
