Phenotype is what the glasshouse shows

Glasshouse Mendel

The commission: deliver one crimson plant that is truly breeding AA, not a crimson carrier. Ruby and Ember look identical but hide their alleles. Cross, retain, test, and infer within four generations and seven bench pots.

Generation 0 / 4 · bench 3 / 7

Ivory proves aa. Crimson alone does not distinguish AA from Aa.

Retained bench

Select one plant to submit, or two to cross.

Parent oneChoose a retained plant

Parent twoChoose a retained plant

Deterministic litter

Retain or compost every seedling before another cross.

Four-cell test bed

Enumerates both gametes from each parent.

Select a crimson candidate and the known ivory tester, then run an exact test cross.
