Five factors affecting H W principles are- 1natural selection(of adaptive variations) 2mutation 3recombination 4genetic drift 5gene flow or gene migration

Sewall wright effect is the change of genetic constitution of an area due to immigration or emigration

THANK US SOO MUCH MAM FOR THIS AWESOME CLASS. HERE ARE THE ANSWERS OF ASSIGNMENT: 1) SEWALL WRIGHT EFFECT: It is nothing but a other name for "Genetic drift". This effect is named after American geneticist SEWALL WRIGHT. It is the change in frequency of an existing gene allele in a population due to random sampling of organisms. In some cases it can cause rare alleles to become much more frequent and in due course of time it even fixed in the environment. 2) Five factors affect Hardy - Weingberg principle are :- - No mutation - No gene flow (Gene migration) - No genetic drift - No genetic recombination - No natural selection pressure. Sorry mam for late submission of homework.

Thank you Mam for such wonderful session ❤ SEWALL WRIGHT EFFECT OR GENRTIC DRIFT - change in frequency of existing gene pool in a population due to random sampling occur by chance. ❤❤💕 FIVE FACTORS THAT CHANGE HARDY WEINBERG PRINCIPLE - 1)GENETIC DRIFT 2) MUTATION 3)RECOMBINATION 4)GENE MIGRATION 5)NATURAL SELECTION ❤

Thank you so much ma'am for wonderful session 🙏🙏 U r d besttttt ❤❤ Today's answers: 1) Sewall Wright effect also known as genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms. The alleles in the offspring are a sample of those in the parents, and has a role in determining whether a given individual survives and reproduces. 2) 5 factors needed for Hardy Weinberg to remain in equilibrium are: 1-- a large breeding population 2--random mating 3-- no change in allelic frequency due to mutation 4-- no immigration and emigration 5-- no natural selection

Pta nhi log saare lacture kyo nhi dekhte...... Mam mind-blowing teaching

Sewall Wright effect is nothing but genetic drift.. Hardy Weinberg equilibrium is affected by 1. Gene migration / gene flow 2. Genetic drift 3. Mutation 4. Genetic recombination 5. Natural selection

Ma'am you are supercool. What an amazing lecture 💗.

thankss mam pray for syria 😭😢😢😭😭

Thank you so much ma'am 😍😍😘😘😘😍😘😍😘😍😘😘😍

I thnx to all vedantu teachers who help us to make our study easy nd simple☺

Mam I am not able to join vedantu learning app what should I do

Meri pyaari pyaari vaani mam 😌😌🌹🌹🌹

Charles lyell is also who influenced darwin

dna fingerprinting is not finished some main points is not complete

*happy independence day Vadantu MadeEjj Medical family and all my dear friend*

Very nicely explained

Well explained MADAM

mam plz batayie live class kaise join kru mujhe pata nahi hai plz plz plz mam reply

Thk u......very much mam.....😇😇😇....aapne wo graph ku to asaan tarikhe se samjhadiya....aapka teaching way..... outstanding hai...5⭐️..😇😇😇

Thank you so MUCH mam super amazing session and super fantastic... explain.....a LOTS OF THANKS AND LOVE YOU...mam.... crystal CLEAR.....👍👍👍👌👌👌🙂🙂

Awesome session mam 👍👍 I enjoyed a lot 😊😀

Thanks a very lot mam

Thanku mam nice having sessions with u a lot of knowledge gained

Thank you so much mam super amazing station 🤗🤗😚😚

Thank you mam

Mam wow what a session...especially hardy winberg...thank u so much

Please vedantu team... Make a playlist series of MOLECULAR BASIS OF INHERITANCE

Amazing mam

Mam please come fast I am full energetic when I see u teach in front of me

Thank u teacher u come soon thank u so much we miss u

Random change of allelic frequency in a population which occur randomly or just by chance is genetic drift and is also known as Seewal Wright effect.the two forms of Seewal Wright effects are founder and bottle neck effect

Mam Apne jo example diya sereiya wala usme gene migration ku nahi ho Sakta. gene flow hi ku?

Love ur teaching ..mam 😘😘

Love u so much mam😘

best graph explanation

Hello mam... Thank u for this ossam class..... Missing uhhhhhhhhhhhhhhhh so much mam😔😔❤❤❤❤❤

wonderful mam . Tnq so much for the videos

Mam bahut maza aaya class mein 🤗🤗🤩🤩🙌🙌... Once the class was ✨Fabulous

5 factors are gene flow,genetic drift,mutation,genetic recimbination and natural selection

Hlo mam waiting eagerly to see u

Five factors are known to hardy Weinberg equilliibrium these are gene migrated gene flow genetic drift mutation genetics recombination and natural selection

wow .

Vani mam circulation cptr ka playlist bna digiye n mam

Well explained mam !

Genetic drift gene migration mutation recombinant natural selection

Thank u so much mam because of i m in dental clg sorry mam mbbs nhi hua. Mam can u suggest me some books for dental plz mam nd how to study plz mam help me

The original drifted population becomes founder and the effect is called founder effect

Thank you mam . It's crystal clear but I can from andhra Pradesh so I can't able to understand hindhi perfectly so plz teach in english

Mam 3:57 ecoli replicate/reproduce in 20min not 16min

Mam where is the 4th class of Evolution ???

Thanku mam assume lacture mam

Mam your classes helping me a lot & your classes are amazing

Hello mam

Lecture starts at 2:40

gd afternoon mam

Mam m Soo excited for this lecture....🥰

Mam mujhe kiss class ka video ka notification 2 din see nhi mil rha hai

Genetic drift

love you a lot mam... you are amazing..really hats off for your efforts

issue there only 4 lecture of evolution

Mam for example dinosaurs, they are extinct from world ☺

Mam aapke bal. Curly hi thik tha

Nice

Thank u so muchh ma'am

THANK YOU SO MUCH MAM...😍😍

Mam gher valo ne mujhse mera mobile chhine liya he ab me kese padhu

🇮🇳🇮🇳🇮🇳🇮🇳 Aavam 🇮🇳🇮🇳🇮🇳🇮🇳brand new channel by vedantu is coming to change the way we study...:)))) keep following

✔️✔️❤❤😘😘

Vani mam :- Is it clear ? Me - Ha it's clear !

Hlo mam

Plzzz mam thodaslow bolo

Slow bolo mam

11:23 -11:30 Mam is like Dora the explorer🤪

Mam your lectures are super duper awesome..... 💕💕
