Very good better best Mahanta sir

[@shinchunaughty2475]

Recombination frequency can not exceed more than 50% and after 20 map units recombination frequency decreases with each additional map unit it won't be 60 map units for 60% coz it won't reach to that level

[@chaudharyvikasbhambhu2104]

U explained it very simply and in easy way.....thanks a lot

[@biplabchandrasarkar4095]

Very excellent lecture for understanding Lots of thanks maam

[@rajarshinapoleonbonaparted4940]

Ma'am this video is amazing for clearing my doubts, but I'm still confused with how to find the order of the genes , like what are the points we must focus on to find the order of the genes ? And on the last part of finding the order of the genes based on interpreting the given measurements of distances between each gene, you asked us to consider the one which only has least distance between 2 genes, I did not understand this, may you please explain to me why ?

[@dskb760]

I must say it was awesome. I shall recommend this video to my friends also. Thanks a lot for this informative video.

[@Anurag9344-q1i]

Those who are saying that how she changed AbC to Abc and aBc to aBC - *Actually both the questions are different. In the first question the gene order is ABC whereas in the second question it is BAC.* *Therefore double crossing over in case of BAC and bac would result in BaC (or aBC) and bAc (or Abc).* However she forgot to change the sentence - "crossing over between B and C" to "crossing over between A and C" in the second question. Since crossing over is not possible between B and C in case of BAC.

[@bmcommando9064]

Thank you so much for your explanation...

[@shinchunaughty2475]

Excellent explanation

[@BhargishNandanGogoi]

Mam why did you changed the double cross over Genotypes from aBc / AbC to Abc/ aBC during the last part where you’re finding the Gene order ?

[@debishabiswas4858]

Yess I guess it was a mistake that she use single crossover genotype for finding order sequence of gene

[@Anurag9344-q1i]

​@@debishabiswas4858 It was not a mistake. Those who are saying that how she changed AbC to Abc and aBc to aBC - *Actually both the questions are different.

[@mahimasankhala5403]

You have mentioned that if recombination frequency is 60%, then map distance will be 60 MU. But 60% recombination frequency is never possible. and btw, nice explanation, I've prepared so many topics for CSIR-NET from your vedios. Thanks!

[@debanjanbhattacharya1956]

Exactly you have got this one right.. She has explained it wrong Although the distance is 60cM the recomb freq will be still 50% After all its the whole dilemma between crossing over and independent assortment 😅

[@lipipragyadevi]

Exactly maximum recombination can be 50 percent

[@Muzee123]

Pyq on this topic plz. Pyq is important mam

[@minimedicalbiology9330]

The genetic map for three genes A, B and C is as follows: A‐B = 10 map units, B‐C = 5 map units and A‐C = 15 map units. In an individual of genotype AbC/aBc, the percentage of gametes expected to be Abc is (assume no interference) 1. 0.25 2. 0.5 3. 2.5 4. 5.0 ans please

[@palwindersingh1398]

[@factpoint663]

Mam your teaching method is too good.....excellent ❣️😍Mam aapka hair real hai please bta dijiye🙏

[@ajitkarki8286]

Love from Nepal

[@santoshhuded9688]

@ 7:54 65 % recombinant frequency can never be... Becoz mac recombinant frequency is 50% and minimum is 0%. .How much it may be 65,75 mp always recombinant frequency is 50%.

[@kashisharora7572]

Best explained 👏

[@animeshpatra6877]

Thank you mam.

[@bagangmartha6858]

you're such an amazing teacher.....❣❣❣❣❣

[@archieducation]

Lov u ma'am ..Thanku so much 😍😍🙏

[@eatandrepeatt]

Respected Mam, In two point cross over, how we will find the order of gene ? 🙏🏼

[@khushboosingh9823]

Ma'am thanks a lot

[@kalyanlohar476]

Thank you maam... Thank you 💞💞💞🙂👍

[@conceptum4250]

Double cross mai capital B and C sath hain ya B ar small c.Gene order BAC hai ya ACB? Agar ACB hau to AC ki distance =12.6, CB =12.3

[@MayankSingh-sy9iw]

Recombination frequency and chances of crossing over isn't same thing .....even chances of crossing will always be half of recombinant frequency

[@diyachawla8092]

Thank you so much ma'am

[@nilimahati438]

I have a request mam...please tetrad analysis pe ak lecture uplode karna please.....utube pe us topic pe koi best vedio nahi ha jo csir ke liya best ha....lekin up hi ho jo ham logi ko samjha sakti ho...please mam...😚💌

[@abhijitaher1515]

Mam you told about gene order but in double cross over two capital letters don't come together

[@ankitachowdhury5268]

Mam thnkyou so much for this video.....love this video....mam plz aap csir k genetics wala part parha dijiye.....pedigree wala part....

[@BansalBiologyAvantika]

I have already made video on pedigree

[@SelimMostakAhmed-ej9yy]

Mam middle ke B and C gene switch hone ke baad A bich me kaise Gaya yeh samajh nehi aya please samjha dijiye

[@nirupamapradhan2107]

Happy Teacher's Day Dear Mam 😊

[@BansalBiologyAvantika]

Thanks a lot

[@pratitkumartripathy5144]

At 26:05 the gametes of Double crossover are different and at 27:57 it's been changed carefully. Confusing!

[@jiajiarre]

Exactly

[@Anurag9344-q1i]

​@@jiajiarre Those who are saying that how she changed AbC to Abc and aBc to aBC - *Actually both the questions are different.

[@aviksarkar6138]

In the last part between two possibilities why choose the 2nd one not clear fully - if possible explain in the next video...

[@pratitkumartripathy5144]

As per the earlier table.....B/b is in the middle and not A/a

[@sumayashah8564]

How u Change alles of double cross ?? Plz check it again

[@37shuvayandasgupta64]

Thanks a lot ma'am.

[@AvinashKumar-ii5dy]

Wow, what a great explanation as if you've got a lot of teaching experience !!! Amazing. Starting from basics you taught this problem. It seems you've command over genetics topics. Good. Despite a lot of study material available online, but the teaching with such an ease and perfectness that any body listen to your video, will definitely understand the topic. Thanks a lot Guruji. Could you please help me out in solving one more problem please. In an experiment involving mapping of 3 genes (a, b and c) in Drosophila, a threepoint test cross is carried out. The parental cross was AAbbCC x aaBBcc. Thegenotypes of the double crossovers are: Aabbcc and aaBbCc. Based on this,determine the order of the genes.

[@priyankaguleria9518]

Gene order is ACb/aCB (confirm it by making double cross over and the answer will be the same as given the value of dco in question)

[@rajghosh4485]

Amazing.. 😊

[@AnuragAnand-lw5lz]

mam there is error in genotype , priviously you have written something else but later you changed .during distance mappinhg . i am not getting it properly.

[@purnashaghosh4730]

Thank you ma'am

[@BansalBiologyAvantika]

Most welcome 😊

[@buggmenot5581]

On the three point cross gene order I didn't understand why A has to come in the middle ? B is getting changed during the double cross but won't it stay in the same position? Like why the gene order is not aBC instead of BaC? Nway love your classes and you are gorgeous 😂🙏

[@ruchisharma7988]

Same doubt, ekdum se kaise ho gya ...

Same doubt glti krdi mam ne dhyan nhi rha

[@subhasmitaacharya7571]

Mam can I depend on this playlist to solve the pyqs of inheritance biology?

[@srikantadash4603]

Please make a video in English mam. My friend don't understand hindi

[@ruchisharma7988]

BAC gene order samaj nhi aaya... crossing ho gya then, a bich me ayenga then captain mess up ho gya , iske Bina kuch bi ans. Nhi nikalega

[@Raza-Graphy-Fan-Records.]

MUCH APPRCIATED

[@Dse629]

Can you please make a video on mitosis and meiosis for csir point of view

[@BansalBiologyAvantika]

Sure

[@pratitkumartripathy5144]

How can a gamete of double crossover formed from ABC/abc earlier will give gene order as BAC/bac.

[@manjushdevnath7403]

Mam apko gene order (BAC and bac) yeh apko kayse pata laga pehle se?? Please reply please bohot confused hu mai.!

i was confused in last question you took double cross this Abc and aBC but it is AbC and aBc so i confused in this please clear it

[@AbhishekSharma-ny2wu]

Right 😅

[@tanialovesillustrating4312]

Same question

[@adilaaroojtahir9280]

I'm still finding answer of this qstion 😐

[@SimranThisSide]

Idk why I've always learnt that crossing over always occurs in non sister chromatids of homologous chromosomes in pachytene stage of prophase 1 of meiosis... And even the Google says this

[@prakashmahanta3503]

Thank u so much mam

[@laibaahmad2361]

No, that statement is not necessarily true. The concept of "double crossing over" in genetic linkage analysis doesn't imply that the lowest recombination frequency is associated with double crossovers. In fact, double crossovers would typically result in higher recombination frequencies.
