Ma'am if Allopolyploidy is forming an individual with 2n means then how it falls under polyploidy. Polyploids r those individuals having more than 2 sets of chromosomes ri8 like 3n 4n etc.,
Mam we learned that chromosome no. does not double during interphase, only DNA doubles. Then how come it goes from 2n to 4n after colchicine treatment?
Yes only DNA content gets doubled during interphase. colchicine doesn't allow the formation of spindle fibres. so the chromosoms are not pulled to the opposite poles and the chromosmes are not distributed to daughter cells and remain in the parent cell only.
@@Studywellelearning please explain how I am confused... 2n mean 2 sex chromosomes and n means 1 from diploid so 2+1=3 which is equal to 47 so how it becomes triploid?
This is the best explanation I have found on this topic so far. I understand it now. Thank you so much for the clear lecture.
😊
Ma'am, you've explained the concept with great clarity. Thank you so much.
Your method of teaching is very good

Amazing lecture
Glad you liked it
Awesome
Tnk u very much.
Mam I will be very happy if you add different types of alloployploidy.
Superb mam💓
Very Nice Explanation😊😊 Thank U Ma'am
Like the way ur concept thanks
☺️
She is so underrated.. Really good teacher. 🙂😌
Thanks 😊
@@Studywellelearning mam I have a question kindly reply.. Can non-disjunction occur in allopolyploidy..?
@@anamika13 yes, wherever is meiosis and pairing . non disjunction can also occur.
@@Studywellelearning ok thanks mam. 😊
Wow
Mam you have wonderfully explained this topic👏👏
Thanks
❤❤❤ tq mam

Yes you are right ' polyploids have more than two sets of chromosomes
@@Studywellelearning Ma'am even I am a lecturer. I also make so many mistakes. 😊ty for making this wonderful video.
Thank you ✨️mam✨️🙏🙏🙏🙏🙏
Thanks ma'am 😊
Thank you so much mam
Thank you mam...

Can u tell me da difference between monoploid and haploid
consider a hexaploid(6N) cell, for it, monoploidy = N but haploid number will be= 3N
But mam S phase me toh sirf DNA double hota hai chromosome ka toh number wahi rahta hai wo split karta hai Anaphase me tab double hota hai
Yes. That's right
Mam we learned that chromosome no. does not double during interphase, only DNA doubles. Then how come it goes from 2n to 4n after colchicine treatment?
Yes only DNA content gets doubled during interphase. colchicine doesn't allow the formation of spindle fibres. so the chromosoms are not pulled to the opposite poles and the chromosmes are not distributed to daughter cells and remain in the parent cell only.
this leads to formation of a polyploid cell.
Wow.. I understood t concept. Tqq u mam..
But there is only 1 chromosome increase in zygote so how you called it a triploid?
No, it's increase in the whole set of chromosome.
@@Studywellelearning please explain how I am confused...
2n mean 2 sex chromosomes and n means 1 from diploid so 2+1=3 which is equal to 47 so how it becomes triploid?
@@NatureScenicViews 2n means two sets of chromosomes.
@@Studywellelearning that's what I am saying....
@@NatureScenicViews set means haploid number of chromosomes or one genome.
Sound is very low....
Number mam nice explain 😇
can you please explain everything in English. thank you
Can you explain euploidy please huhuhuh
Yes , In this video I have explained it.
