Finaly i found a teacher who explained each and every topic very clearly thank you so much😂❤

Remember the dominant traits with-- "GRAVITY"👍:) G- green fruit colour R- round shape A- axial flower position V- violet flower colour I- inflated pod shape T- tall plant shape Y- yellow seed colour.

Mam these topics are left.... Please go through it too...... A humble request 🙏🙏🙏..... (1) polygenic inheritance (2) Pleiotropy (3) Colour blindness (4) Thalassemia (5) Chromosomal disorder - aneuploidy , Polyploidy

Ma'am please start molecular basis of inheritance... It's a bit tougher and the weightage is also high...

I really found the best teacher in my entire education journey the quality videos which you're providing is far better than byjus,... And we're getting such videos for free, we're really lucky to have you

Pleiotrophy and polygenic inheritence are missing topic ...read it from ncert.

Any Boards student here❤

Mam aapka pdhane ka trika gjb nahi mgagjb hai lajvab hai

Thank you ma'am for this amazing explanation of chapter

Mam actually few topics are pending in this vedio e.g colour blindness, DNA fingerprinting, pleiotropy,polygenic inheritance etc

Mam crossing over to fertilization me honi chahiye...but meiosis me kaise parents ke homologous chromosomes cross over karte hain??

Notes which are written in video is Enough for boards????? Plx reply

Mam you are really doing a great job 👍👍 But please mam ek pyq series jee/neet wale baccho ke liye bhi lao jisme aap past ten years ke most expected questions karwana. Plz mam i hope you will understand my text🥺

Bench of (2023-2024) like Kare ?

I really love your explanation mam, I was average but increasing up my rank now, all thanks to you, I really found a gem in a face of a teacher

she made it really easy, Although it is one of thre toughest chapter of 12th botany......HATES OFF MAM❤😮

Mam app All in one ho. App to sabhi subjects padhati ho for example physics, chemistry, biology . Aur sabke doubts ko crystal confuse kar deti ho . Jis bacche ko kisi subject me doubt nhi hota hoga use bhi Crystal doubt full bna deti ho . Well done 👍 Keep doing ab doubts Crystal clear nhi ❌ Create crystal confused to all the student But app bacchho ko Gyan de rhi ho besak confuse karke ye bahut accha kaam h.

Such a great teacher who is actually doing hard work for students and providing best lecture absolutely free

Thank you so much ma'am sach me concept huye crystal clear finally just a week left for my bio exam and i completed my whole syllabus just by watching your videos used to think bio a hard subject but no one can teach bio the way u did hats off to you ma'am ✨✨

The way you express and the dedication you have creates the curiosity and eagerness to know in depth of each topic also you provide the deep core contents of each chapter.Also I request you to provide the deepest concepts from each chapter so that watching your video and then revising would be more than enough for exams provide such CONTENTS ...ALL I CAN SAY IS you are mesmerizing and unique from the crowd 💕💕💕🔥🔥
