I’m regularly sharing Important PYQs here on X - how to remember them/understand them - here is one post from last year incase you missed it.
How to differentiate between Edward and Patau.
Pa (प) se Patau.
If you hear the pa sound - it’s in Patau. If not - it’s Edward.
Holo‘p’rosencephaly, Polydactly, Polyscystic kidney, Cleft ‘P’alate, cutis a’P’lasia- all are in Patau.
You don’t hear ‘P’
Rocker bottom feet, horse shoe kidney, clenched fist with overcrossing finger - It’s Edward.
(Also- E=Eighteen- Edward is Trisomy 18, P= Patau= puberty- which starts at 13- Trisomy 13)
