six years later, this video have saved a student like me having a very hard time understanding her lessons in developmental biology thru online class. I have been binge-watching almost all of your developmental biology videos. Thank you so much sir Shomu!
All hail our lord and savior Shomu who in our time of great need saw in his omniscience to create these youtube videos to save us from failure or worse. We should reply in kind his blessings by subscribing and liking his videos.
Wow! that was awesome! Cleared all my doubts! Especially the cytoplasmic inheritance from mother which dominates over the gamet's gene during initial development!
Attention all, this video is does not explain the maternal effect. Shomu is explaining cytoplasmic inheritance, it is a very good explanation though! Maternal effect is different
Hello Sir, thank you for explaining this topic in such an easy way. But I have a query. I read in a book that in f3 generation the ratio becomes 3:1 i.e 3 snails become dextral and 1 snail becomes sinistral. Can you please explain why ?
Hello sir u r saying cytoplasmic inheritance and maternal effect are different but u give the same snail shell example in cytoplasmic inheritance video also........and the another thing is as we know in most of the case a protein is not remain stable for longer time then how few cytoplasmic protein which only available once no new generation of that protein as no gene available then how they complete whole evolution process??
What will happen sir when these proteins will be exhausted in cytoplasm of dd genotype offspring. Then will the coiling change in future as then the proteins will be produced for sinistral coiling?
Sir, in F2 generation, for dd type of offspring as you mentioned the phenotype will be of Dextral type by virtue of the cytoplasmic proteins. But, since the genes are of sinistral type won't they code for sinistral proteins eventually?
Sir, This video was very helpful to me as it was explained in a very efficient manner. Would you please do a video lecture on Nerve Conduction mechanism along with graphs
I have one confusion..Father that has sinistral type must be born from a mother, then why he has sinistral tpye, why dextarl protein not expressed in him? Plz explain.
Hello, Shomu. In case that the mother's phenotype is sinistral shell coiling (genotype is dd), will all her offspring have the same phenotype as her even if her husband has a dextral shell coiling (let's say a DD genotype)? If yes, then what would happen if the F1 generation is self-crossed (Dd x Dd, in which the female has sinistral shell coiling and the male has dextral shell coiling)? Will the offspring with either a DD or a Dd genotype also have sinistral shell coiling?
The F2 generation will have all dextral since Dd mainly codes for dextral. D is dominant over small d and remember only protein for dextral type is inherited from mother by cytoplasmic inheritance. So intercross between Dd (sinistral) since mother is sinistral, will give Dd dextral in F2
Dear sir kindly tell me s+s+ male dextral cross with ss female sinistral result f1 generation all are sinistral because of maternal effect i agree but self cross (s+s@s+s) self Cross produce progeny (1s+s+ , 2s+s, 1ss) all are dextral, why this , it should be follows maternal of male effect, if possible explain this is given example in gene viii book

Have Read several books still confusing, but this lecture made it clear in my vision. Thank You sir so much for your efforts.
I was unable to understand the dd(dextral) in F2 generation but your lecture clear my doubt.
Sir thank you very much.
You are doing a great job.
Tysm sir ☺️ now this helpful for my exams
You're welcome. Glad to hear that you're getting benefit from my lectures
@@shomusbiologyofficial ☺️👍
So true! Helpful for my upsc options preparation. Thanks so much!
i love your explaination. so clear. thankk you. so useful for college students
You're welcome

Sir aapki English bhi ache se smjh आती है thanku sir ji
Thank you so much sir for helping us... May God bless you always sir!🙇♀️🙇♀️❤
You're welcome
Great vids man you make it so clear for me!
This video helpes me after 6 years of upload
It will be evergreen
Attention all, this video is does not explain the maternal effect. Shomu is explaining cytoplasmic inheritance, it is a very good explanation though! Maternal effect is different
We're covering this in my plant genetics class now, and this topic is kind of confusing. Thanks for posting this video.
This video is really very helpful
..Sir...
You're welcome
Thanku so much for the amazing class🙏🏻🙏🏻
You're welcome
Your explainetion always clear my concept thank you so much sir
Thank you

You're welcome
Thank you. Soo much,
Could you please give an example of a
maternal inheritance and a multifactorial inheritance trait or disease?
the concept is clear.. Thanks for this video
You're welcome
Tahnk You sir, this explanation was very helpful.
Thank you. You never forget to acknowledge
Wow very impressive explanation!
Thank you so much for appreciating my efforts
Proteins are coded by dna ,in this f2 generation last one has ressive gene how it produce the dextral protein,how the snail was dextral
Hello sir
I've a question
What is the phenotypical ratio of F2 if the male is dominant and female being recessive.?
Ur an excellent teacher
Thank you
Very nice,many thanks, may you live long
Thank you. Glad you liked my lectures
Sir, in F2 generation, for dd type of offspring as you mentioned the phenotype will be of Dextral type by virtue of the cytoplasmic proteins. But, since the genes are of sinistral type won't they code for sinistral proteins eventually?
Yrs they will code but dextral proteins dominate sinistral proteins
maternal contribution in early embryonic development? Is question me ye hi answer aayega kya plz bta do

Thank you sir very much you saved my exam today
You're welcome. Glad to hear that you're getting benefit from my lectures
Thank you so much sir you are my savior at the last moment of my exam 😭❤️😊
You're welcome. Glad to hear that you're getting benefit from my lectures
thanks! that was a perfect explanation!
Thanks a lot for this wonderful effort 👍
Thank you so much 😊 Sir 🙏
You're welcome
Sir, what is difference between maternal effect and maternal inheritance ?
Sir then why all progenies are dextral in f2 when sinistral is taken as mother and dextral as father
Sir,
This video was very helpful to me as it was explained in a very efficient manner.
Would you please do a video lecture on Nerve Conduction mechanism along with graphs
This was so so helpful THANK YOU SO SO SO SO SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You're welcome. Glad you like it
Sinistral type of shell coiling is because of absence of dextral protein? Is there sinistral protein?
No
Very efficiently explained 🤓
Please sir provide us written notes on this topic. It is very helpful for us.
I have one confusion..Father that has sinistral type must be born from a mother, then why he has sinistral tpye, why dextarl protein not expressed in him? Plz explain.
same confusion
Sinister coiling appears in f3 generation
Superb lectures
Thank you

Hi kya ap kiska f3 generation explain kr ssakte ho....sir
Hello, Shomu. In case that the mother's phenotype is sinistral shell coiling (genotype is dd), will all her offspring have the same phenotype as her even if her husband has a dextral shell coiling (let's say a DD genotype)? If yes, then what would happen if the F1 generation is self-crossed (Dd x Dd, in which the female has sinistral shell coiling and the male has dextral shell coiling)? Will the offspring with either a DD or a Dd genotype also have sinistral shell coiling?
I also have the same question
No the phenotype of offspring of f2 generation is dextral
The F2 generation will have all dextral since Dd mainly codes for dextral. D is dominant over small d and remember only protein for dextral type is inherited from mother by cytoplasmic inheritance. So intercross between Dd (sinistral) since mother is sinistral, will give Dd dextral in F2

sehr hilfreich! Greetings from Germany
What about the f³ generation??
Kl mere exam hh aj meko abhi smjh aya hh 😂....thanks sir
All the best
Can u plz suggest me a book for these topics of genetics extrachromosomal inheritance
Thank you for this
You're welcome
love u ma man ..I am confused with maternal inheritance and complete dominance,,is they similar?
This was big help Thankyou
You're welcome
Bro can U explain F3 progeny and what will happen if we interchange parents? I studied this but was not able to understand this properly in F3 cross .
So all offspring of a dd genotype mother will be sinistral...Am i correct? please reply
If we a cross a dextral male with sinistral female what happen plz explain
gais . what is the difference and similarity between maternal effect and maternal inheritance ?
Plz tell us...
Very well explained.

Please tell what happen in f3 gen
Sir could you please explain upto F3 generations...yhankyou
Also the reciprocal of it...
Helpful for exam
wow, thank you so much!
great!
what's Centra dogma?
plz tell me.
Sir chloroplast mutation and mitochondrial mutation ka video he to link vejo sir please
Not yet
@@shomusbiologyofficial okkk
You r god man😍
Thank you for watching the lecture
it was really helpful !
what is the difference and similarity between maternal effect and maternal inheritance ?
What would the F3 generation look like?
yes, what happens with dd mothers offspring? Do they still have enough proteins to overcome the genotype?
Then both sinistral and dextral will appear in 3:1
what about sinistral female???as parent
excellent explaination
+Tekram Pradhan thank you
