In other species: ass (donkey) , horse , goat , sheep , water buffalo

Categories: Embryo phene

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: A foetus in which the edges of the somatic disc in the developing embryo have curved upwards instead of downwards, resulting in the viscera floating free in the amnion. The head and the tail are curved up towards each other. Dystocia is the usual result.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
