I was thinking about this and I thought this won't have a proper answer in google Anyways I googled and found this video. You understood what confuses us and made videos accordingly I'm grateful
thank you, sir, great vid, one thing though, some sources I sited say that multiple allelism can only be considered when more than two alleles determine the dominance of one gene, and two alleles is just normal allelism.
At 5:52,as u said sir AABBCC is Whitest Skin n aabbcc is darkest skin But In case of AABBCC there is 6 Dominant genes that means more no. of Dominant genes -more no.of melanin Formation occour that leads to More Black( i,eDarkest ) n In case of aabbcc there is no Dominant gene tha mean no melanin Formation leads to Albino Skin(white colour). My doubt is Sir AABBCC leads to Whitest or Dark Skin colour??
Sorry to say sir....u r the best teacher but i think there is a little mistake probably i m wrong but i think capital letters using for the dark skin while small case letters for light skin
an allele is present on the same locus of homologous chromosome, and we only have a pair of homologous chromosomes, then how is it possible to have three alleles of a same gene??
+Chandrachur Mukherjee there are no three alleles. There are two alleles but the mixture of those two give rise to the third kind like we see in blood group determination.
Three alleles are present among whole population but at any one time in every individual only two alleles Are present. For example a person may have allele A on one chromosome and allele O on anther chromosome of a pair and will have blood group A. Another person may have Allele A and Allele B and so on. Shomu has not talked about allele O the third allele for blood group phenotype. He is talking about only two alleles and calling it multiple alleles. Multiple allele phenomenon is used when a gene has more than two alleles.
Well...No doubt you r a great teacher but this VDO actually confused me... Coz my textbook is saying something different 🤔 It is defining multiple alleles as *More than two forms ( alleles) of a gene in a population occupying the same locus on chromosome or its homologue are known as multiple alleles* Can you or anyone please explain..🙃
Sir, i got that multiple allelism is due to interallelic or intragenic interaction but what about polygenic inheritance?? Is it intragenic or intergenic... I had a bit of confusion in it?? Pls help...
sir, like in TT and Tt both plant have same height similarly is it possible that persons having AABBCC and AaBbCc skin colour gene have same skin colour. if no then how can two similar dominant alleles(A and A both) can work at same time?
Thank you, I have an exam tomorrow and I was confused with the difference. You saved my life

Thanks, good review material for my lab bio class.
Thank you so much...Topic is crystal clear
You're welcome. Glad to hear that you're getting benefit from my lectures
Thank you sir.. i get almost all answer from your videos
Glad to know that
Very nice thank you very much I liked and subscribed
Thank you so much for appreciating my efforts
Thanks sir🙏🙏🙏
Thank you man you helped me a lot with my bio homework 📚
Glad to hear that you are getting benefit from the videos

At 5:52,as u said sir AABBCC is Whitest Skin n aabbcc is darkest skin
But In case of AABBCC there is 6 Dominant genes that means more no. of Dominant genes -more no.of melanin Formation occour that leads to More Black( i,eDarkest )
n In case of aabbcc there is no Dominant gene tha mean no melanin Formation leads to Albino Skin(white colour).
My doubt is Sir AABBCC leads to Whitest or Dark Skin colour??
Ya I too ,got stuck there ...I referred my book there it is given as you just commented
He actually gave an example 😅
AABBCC leads..to darkest n aabbcc to lightest skin colur.Its written in NCERT too.
this helped a lot! thank you
Glad it helped
Well-explained.
Thank you
Very good overview. Thanks!
You're welcome. Glad to hear that you're getting benefit from my lectures
Lovely explanation
Thank you
Hello sir..i want u to solve previous year question papers after done with the relavent topic
Thank you so much.. it really helped me.
If I have multiple alleles how can I know that these alleles belong to one gene or more than one gene?
Good explanation..Thanks...
You're welcome
Thank you so much sir
You're welcome
Short but informative explanation
All dominant are dark not white ND all recessive are light
Thanks for the responsiblity carried out
+Kefas Amos thank you. Glad you liked my lectures

+Shomu's Biology by mixture I mean when bother the type of alleles expressed
Three alleles are present among whole population but at any one time in every individual only two alleles Are present.

@@shomusbiologyofficial what happens if you have trisomy

Thank you for making this clear to me finally I understand haha
You're welcome
The 38 people who hit dislike are computer students
Thnx sir u clear my doubt
+Harsh Trivedi glad to help you out
Thanks alot ❤✌
You're welcome
Wonderful
Superb
You're welcome
this is amazing
Thank you. Glad it helped
Your voice is good
Thanks Shomu
Ah! Sir i have a doubt that is, is AABBCC is for darkest or brightest??
I liked it , thank you so much.
then what is the differnce between codominance and multiple allele????
in polygenic inheritance AABBCC IS VERY DARK COLOUR AND aabbcc is very light colur time @ 5.55 but u have given opposite sir which is right sir
I think he just gave an example, AABBCC is darkest and aabbcc is whitest 👍
Can you clarify sir which of the statement is correct?
"For each trait 3 or more genes are required"
Or
"Only 1 gene is required for 1 trait"
First one for polygenic
@@shomusbiologyofficial OK Tnx
Thank you so much cleared my doubt
Sir, why crossing over doesn't occur among multiple alleles??
So, an allele is one of many characteristics of a gene. How many exactly?
Thank youuuuu!!!
You're welcome
Thank you. Works for me :)
These vedios are help me..
can you share a vedio about lozenge locus of Drosophila
Sir, i got that multiple allelism is due to interallelic or intragenic interaction but what about polygenic inheritance?? Is it intragenic or intergenic... I had a bit of confusion in it?? Pls help...
Thank you
thank you so much !!
Correction all AABBCC is the darkest form
aabbcc is the whitest one
It's about what we assume. Here he assumes that A is white gene and a is dark gene
Hence AABBCC is white gene
And aabbcc is dark gene
6:02 bro held himself with his life to not say "blackest" skin tone 😂
Thank u sir
Gracias
sir, like in TT and Tt both plant have same height
similarly is it possible that persons having AABBCC and AaBbCc skin colour gene have same skin colour. if no
then how can two similar dominant alleles(A and A both) can work at same time?
How can it possible for plant height it is one gene but in skin colour it involves 3 genes that' the mechanism of polygenic inheritance......
thanks
Thanks a lot :)
I think black and grey are two forms of body colour not eye colours.
Bro i think u mistaken in skintone colour according to genes
nice
finally found my tech support
You're welcome
It's character.. not trait...
Gene controls a character
AABBCC is for darkest and aabbcc is the lightest skin tone you said the opposite
You can choose any one of them. It doesn't matter.
sir can i take RR(round) nd rr(green) for monohybrid cross ???
No.
The recssive lead to the albino and dominant lead to black not recessive lead to the black colour
sir in a diploid how many maximum allele present??
jaydipbhai vala allele of one gene is present in each chromosome in a homologous chromosome.
AABBCC is the darkest skin tone( Pure black) and aabbcc is the whitest skin tone i.e albino. You wrote lil opposite Sir
It's about what we assume. Here he assumes that A is white gene and a is dark gene
Hence AABBCC is white gene
And aabbcc is dark gene
AABBCC is the darkest skin tone
Gud
Got it
Dominant gene cause dark skin tone , and light colour is recessive character
1- In polygenic can we have 2 genes? , 2- also in multiple alleles can we have 2 alleles?
Do you even realize the meaning of this video.....?
Recessive not reccesive
AA BBCC DARKEST
aabbcc lightest
Exactly, i was confused too
Pure black parent genotype is AABBCC
thanks
You're welcome
