Three traits, three crosses. Tap every box to work out what the odds actually are. 🧫

Lab note. These are the classic textbook traits, and they make lovely clean squares —
but in real human genetics almost none of them are truly single-gene. Tongue rolling shows up
in people with two non-rolling parents, earlobe attachment is continuous rather than binary,
and eye colour involves at least a dozen loci. Mendel got the maths right; humans are just
messier than pea plants.

Here is the part Mendel never got around to modelling: whatever the alleles come out as, I would run this cross again every single generation.
