Git Embryology Mcqs Page

✅ – Tags mark significant developmental stages for reference.

A) A checkpoint in cell cycle B) A permanent developmental event recorded in history C) A temporary folding event D) A failure of neurulation

A) Normal B) Homeotic transformation (e.g., Hox gene mutation) C) Gastrulation D) Fertilization

✅ – Merge conflict = abnormal morphogenesis (e.g., persistent truncus arteriosus). git embryology mcqs

A) Deletes mesoderm B) Creates an independent developmental lineage from a common ancestor C) Merges endoderm and ectoderm D) Reverts to zygote

git merge endocardial_cushions --squash (squash = combine all cushion commits into one) models: a) Normal cushion fusion b) Failure of fusion c) Atrioventricular septal defect d) Aortic stenosis

A) Revert = apoptosis and compensatory proliferation B) Reset = true regression to earlier state (rare in mammals) C) Both are possible in different contexts D) Neither ✅ – Tags mark significant developmental stages for

✅ – Revert (e.g., cleft palate repair via new tissue) vs reset (e.g., axolotl limb regeneration). Topic 5: Advanced Analogies 13. What does git cherry-pick model in development? A) Horizontal gene transfer B) Transplanting an organ from one stage to another (e.g., induction) C) Cloning D) Polyploidy

✅ – Cherry-pick = taking a specific developmental event (commit) from one lineage into another.

A) Normal development B) Failed fusion → cardiac bifidum or septal defect C) Successful looping D) Aortic arch regression Topic 5: Advanced Analogies 13

✅ – Merging two branches models bilateral fusion events.

A) Surgical repair of congenital anomaly B) Apoptosis of misaligned cells C) Teratogen exposure D) Normal development
