Git Embryology Mcqs ✔ < REAL >

✅ – 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

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

✅ – Stashing = suspended development, changes preserved but not committed. Topic 6: Clinical Correlations 17. A git commit --amend modifies the last commit. Which congenital anomaly mimics this? A) Situs inversus (laterality altered after initial symmetry) B) Down syndrome C) Cleft lip D) Polydactyly

A) Miscarriage B) Dedifferentiation or regeneration (e.g., urodele limb) C) Twinning D) Apoptosis git embryology mcqs

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

✅ – Manual resolution = intervention to correct defective fusion. Topic 4: History & Time Travel 10. git log --oneline --graph in embryology shows: A) Cell lineage tree B) Carnegie stage timeline with branching and merges C) Only birth defects D) Maternal hormone levels

– Squash merge simplifies history but still represents fusion. ✅ – Revert (e

✅ – Merge commit preserves the event of fusion, just as neural tube closure is recorded. Topic 3: Merging & Developmental Fusions 7. Fusion of the palatal shelves (left and right branches) is best represented by: A) git rebase B) git merge palatal_left palatal_right C) git reset --hard D) git cherry-pick

A) git merge B) git rebase C) git branch from a common commit D) git stash

✅ – Amending = altering established situs after early symmetry (e.g., nodal flow mutation). A) Horizontal gene transfer B) Transplanting an organ

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

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) It causes miscarriage in collaborators B) It discards others’ work (anomalies in shared lineage records) C) It speeds up development D) It is always safe

A) A specific milestone (≈42 days, limb buds appear) B) Umbilical hernia C) Decidual reaction D) Zona pellucida shedding

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