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

[AnnuYadav-thvh]

She teaches physics, chemistry, biology and Your teaching style is superb mam 👍👍👍.... Concept hua crystal clear 🙂🙂🙂

[imrahulvlogs]

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.

[janhvipahadiya]

She is answer to all students how says, "when a single teacher can't teach all subjects then how can a single student learn all subjects.
It's really great 🤩
How she can teach all subjects with such perfection 😃

Some legends are watching this for 2025 boards 😅

[ruerue]

Exceptions of dominance law: Co-dominance, Incomplete dominance,
Exception of Segregation law: disjunction of gametes while segregating
Exception of independant assortment law: linkage

[Aaloo_Parathaa]

I love how calmly she teaches❤️❤️ because some YouTube teachers just shout for no reason at all.

[AsTro_FaiZzu]

Welcome for 12th board exam🎉..waste full year without study but during exam we need one short 😂

[Hammerhead]

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

[undefeateddiadem]

Remember the dominant traits with GRAVITY 😊
G-Green fruit colour
R- Round seed shape
A-Axial flower position
V-Violet flower colour
I- Inflated pod shape
T-Tall plant height
Y-Yellow seed colour

[Afzaldadafamily]

This is amazing, one teacher teaching all the subjects.

[nithinkumar]

Her concepts and particularly her language and expressions are just so clear for anybody to understand. She is the best 👌🏻👌🏻👌🏻

[vaibhavmalviya]

🙂Under Three hours mam covered all topics in detail with is not just revision video, if you are starting chapter right now then you may understand full chapter within three hours and your time also saved(instead of watching 20 hours lectures) + Thanks lot mam for quality content❤❤❤❤

[mohdislam]

This is only one of the best video for Principal of Inheritance and
With superr explanation all concepts. ❤

[johannamarianfinos]

12 HOURS TO GO!!!
BEST OF LUCK GUYS....
YOU'RE GOING TO DO GREAT!

[sunitapatel]

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