Multiple alleles vs polygenic inheritance - This lecture explains about the difference between multiple alleles and polygenic inheritance. Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid).
A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance.
So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles).

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??

@user-ue4fp1oi2q Год назад

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.

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..🙃

@MomoSapam-lo3ix 2 месяца назад

Ah! Sir i have a doubt that is, is AABBCC is for darkest or brightest??

@ChandrachurMukherjee96 8 лет назад

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??

@shomusbiologyofficial 8 лет назад

+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.

@shomusbiologyofficial 8 лет назад

+Shomu's Biology by mixture I mean when bother the type of alleles expressed

@anybodyany7409 6 лет назад

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.

@niap404 5 лет назад

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...

@Maria-ph6wb 3 года назад

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"

@shomusbiologyofficial 3 года назад

First one for polygenic

Correction all AABBCC is the darkest form aabbcc is the whitest one

@ASMDxFTW 3 года назад

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

@ankitjaiswal7411 6 лет назад

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?
