It's been almost 3days reading book but couldn't figure it out. Came here and learned it within 7mins. I was confused about the genotypic calculation assuming it and comparing it with phenotypic calculation which gives 1/2(50% hybrid and 50% recessive). Thanks alot, sir.
Answer this 2. A group of stone age farmers settles on a remote island. The allele frequency of this first generation is P= 0.8 and Q= 0.2, with P being the dominant allele frequency and Q being the recessive allele frequency. One thousand years later, no member of this population has the recessive allele. This is an example of: A) Natural Selection B) Genetic Drift C) Mutation D) Gene Flow 3. Which of the following introduced the concept of deep time that everyday processes such as wind and water erosion can account for geological features on Earth today on a long enough time scale? A) Alfred Russel Wallace B) John Ray C) Charles Lyell D) Thomas Hunter Morgan 4. When a new species forms from an isolated population, this is known as _______. A) Sympatric speciation B) Allopatric speciation C) Polymorphism D) Punctuated equilibrium
In a biology class, 65% of the students had the ability to roll tongue. This is conferred by the dominant allele of a gene while its recessive allele, 'n' leads to non-rolling of the tongue. Compute both the genetic and allelic frequencies of the trait in the population.

Let me simplify this video for everyone: Bb and bb are the only available genotypes. the B allele has a frequency of 25%, b has a frequency of 75%. That's it. I don't understand why all these videos are so unnecessarily long.
+Prashant Hariharan each chromosome in a homologs pair will carry the same gene however there may or may not be a different allele present for that gene on the loci on of the chromosome, he's showing 4 chromosomes which have the same gene for eye colour but 1 different allele
So my question to answer is, I have 22 out of 100 people with blue recessive genotypes , and I'm supposed to determine the frequency of blue recessive, and brown homozygous and heterozygous. How do i do this?
He repeats in order to let the keywords reach well our memory. The more you repeat the word (more precisely throughout time), the better it is to memorize.
Idk if the dominant B is recessive over b then the probability of dominant in the new generation may be have 75% according to punnet aqure equation 😢, Can someone help me out of this.
Thank you very much for explaining the notion of allele frequency . Teachers often overlook this part and skip it real quick.

Answer this
The easiest explanation ever! ❤
please make it complicated. please do for homozygous dominant BB. make it three alleles please !!!!!
i swear to god you guys follow my schedule of studying, i just learned these today :)
Haha well I just had a mock exam on them too xD
@Mark Steven probably don't even remember bio classes
@@justkamola you probably don't remember that they don't remember bio classes

at 3:10 you say "there are 4 chromosomes that are carrying this gene in this population"....could you explain this to me again please?

There is no need, there is no need to repeat every other word, word. We heard, we heard you the first, first time.
I feel like he does this for himself to keep him on point...plus it does help reinforce his ideas to the audience.
stfu dont disrespect a legend
He repeats in order to let the keywords reach well our memory. The more you repeat the word (more precisely throughout time), the better it is to memorize.
obviously this is a joke so can people stop being so defensive.
For what reasons is the typical allele not embedded into each cell of the patient?
Please add a topic of mutation pressure
Nice explanation
Find out the allele frequency of A, B and O blood types in a population with the following number of phenotypes.
A=84, B= 109,AB=47 and O=71
you are brilliant.
Thank you so much
I squeal so hard at the things that pop up when I type in bean frequency
Idk if the dominant B is recessive over b then the probability of dominant in the new generation may be have 75% according to punnet aqure equation 😢,
Can someone help me out of this.
this is similar to sickle cell traits.
So... did i get this right:
Alleles are genes and Alleles frequency is the chromosome of that allele out of the whole allele...
thanks
Interesting but verrrrry laboured!
Nice
Much appreciated... This still works even in 2019, lol.
ikr
Who's here in 2021???
anyone from 2023?
2024 xD
lol blib, anyways, this vid really helped me out
harambe Rest in pastalol such good vid lol idk
You shouldn't be a science teacher, Go to Sociology
