## What is Tony Crayfish Worm Genetics?

Can you map a causal mutation before revealing the EMS variants? Tony Crayfish Worm Genetics turns that challenge into a hands-on C. elegans laboratory.

Choose a recessive Ted mutant, whose tail defect is visible only in hermaphrodites, or a Pha mutant with a pharynx abnormality visible in both sexes. Start from a reproducible, seeded founder and follow individual worms through selfing, wild-type outcrosses and mapping crosses.

On Lab Plates, see each worm's sex and visible phenotypes. Select a worm and inspect its chromosome maps in Lab Workspace. Create named strains and return to their worms for later crosses.

Use a two-factor cross to test linkage with a known marker. In three-factor mapping, compare a testcross with a cautious line-plate approach. Place your own proposed causal position on a paired F1 chromosome map, submit an answer, and then reveal the explanation. Your proposed tick stays until you clear it.

Reveal chromosome ancestry and EMS variants when you are ready to check your reasoning. The built-in introduction and guide explain the workflows.

Experiments save automatically on this device. No account or internet connection is required for the simulation. This is an educational model; its genetic maps and sample outcomes illustrate mapping concepts rather than represent measurements from a real strain.

## Version history (last 4 releases)

### 1.3 — 2026-11-10

Version 1.3 introduces a redesigned three-factor mapping workflow with clearer recombinant-line assessment, an evidence ledger, calculated working positions, and improved navigation. It also adds optional streamlined displays, clearer guidance about the teaching model and testcross limitations, and simpler creation of random or reproducible founder mutants. Chromosome visualisation, performance, stability, and the iPhone and iPad layouts have also been improved.

### 1.2 — 2026-11-07

Version 1.2 makes repeated three-factor mapping smoother. When you create a new set of 12 line plates, the app keeps compact phenotype summaries of earlier temporary plates instead of retaining every worm. Plates used for named strains or later crosses remain available.

Saving and worm selection are more responsive. In Time Challenge, submitting your final map now shows your result without the redundant regular mapping question.

### 1.1 — 2026-11-03

Version 1.1 adds Time Challenge. Start with a randomly generated Pha mutant, map its causal mutation using visible phenotypes and marker positions, then submit your chromosome and map position. The app records your time and mapping accuracy and keeps your 20 best scores on this device.

This update also refreshes the Home screen and introduction, improves the responsiveness of final-answer entry, and accepts either a period or comma as a decimal separator.

### 1.0 — 2026-10-31

No release notes.
