Makes it quick and simple 👍And examples make it understandable. Thanks!

omg...dis was d fabulous channel ever watched!! made all concepts crystal cleared in 2 mins

i could not for the life of me understand this when it was taught. this is so simple and helpful. Thank you!

Love videos like this. Clear, precise and to the point. Thank you so much!!! Please post more!!

Lemme help y'all out: Natural selection is: the gradual process by which heritable traits become either more or less common in a population because pressures from the environment Directional Selection is: when individuals that display a more extreme form of a trait have a greater fitness than individuals with average form of the trait. Stabilizing Selection is: when the individuals with the average form of a trait have the highest fitness. Disruptive Selection is : when individuals with either extreme variations of a trait have greater fitness than individuals with the average form of the trait. Your welcome

I'm confused, what's the difference between directional and disruptive selection?

I like how you know all that but can't spell "you're" right bahahaha

Very helpful. I enjoyed the clear definitions and the visual examples with graphs. Highly effective!

Straight and to the point. Loved it.

this was so helpful before my exam, short sweet and to the point

very clear cut and informative video! Glad I found out about your channel!

So simply explained! Thank you!

Love it! Big help, appreciate it!

one of the best i have ever seen

Thank you for this simple explanation!

Great video! Really explained these concepts well.

Great teaching and great examples!

This helped me so much in my exam, THANK YOU

so straightforward it helped a lot

2 mins and great info thanks

Short but effective...to th point..thank you

Nice and comprehensive.

So basically in stabilizing selection,the mean of the population remains unchanged,we just have more individual that express the mean trait.Whereas in directional selection the mean is shifted in the opposite direction from the trait that is selected against.And in disruptive selection,we end up with 2 means with a trough in between,on either side of where the mean would have been had the distribution been normal(like in stabilizing selection).

Thank you so much for this video 😃 Would be very helpful for my bio test👍

Very well explained. Loved it

Omg this was so helpful thank you!!

Wow, very helpful. u just told the whole thing in just 2 minutes !!

It is important to also understand that you need three requirements in order for natural selection to occur: 1) Phenotypic variation: Without variation natural selection can't "select" different phenotypic values, and therefore the population cannot change. 2) Non-random association between phenotypic value (individual phenotype) and fitness (capacity of survival). If there isn't a force (like the ones she mentioned) pushing for one phenotypic value to have higher fitness, evolution by NS will not occur, this is also known as "selection". 3) Heritability: If the phenotypic value cannot be heritable, then the gene cannot be passed to the next generation, and evolution by NS cannot occur.

I like the starting tune.

this helped a lot ... thanks 😃

thank you!!! this is so helpful :)

Thank you for this

thanks so much! i’ve got a bio test tomorrow

Very clear! Make more bio videozzzz!!! PLEAAAZZZ)

Excellent explanation and easiest one.. thanks.😇😇😇😇😇

This video saved my life

Omg thanks for the examples ✿

very informative thanks!

Very well explained dear.. It helped me to explain my sister in her education. Thank you so much dear..🤗

Good stuff!

This is great

U r awesomeeeee 😘😘😘😘 POV u sis from Pakistan 🇵🇰 I was so worried about it I have never caught my teacher at it...tnx a lot 🤠

Right on!

Thanks for this

Awesome intro :D

I have never felt this amount of rage until I had the wonderful idea of trying to understand bio

Teaching me everything my bio teacher doesn’t thank you 😭

thx....much help🥰

Perfect

An amazing video. But the theme song is a bit loud 😂

Wow super......

what does the green line represent?

Please can you answer my question. What is the difference between stabilizing selection and disruptive selection. Because the way you and my teacher explained it sound the same. . . . . I might have an idea the difference please let me know if I'm correct. So stabilizing favors the popular traits in a population and disruptive favors the rare and popular traits in a population but not the average. . Please reply with an answer if i'm correct because I don't want to confused Thank You.

I like the intro ;)

Thanks! :)

good video

If you had an organism that could have its genetics changed at will by an outside force, say a mad scientist, but at the cost of not being able to reproduce, only rebuilt, starting as something akin to a single cell, what selection factors would still affect the organism? The need for energy The need to move to the energy source The need to notice changes in its environmental ... And are these called "selection factors" or should I be looking for a different term? Thankyou

Simpler conclusion: directional selection - only one can survive Stabilizing - smallest and biggest can’t survive, only the middle can survive Disruptive - middle can’t survive, but the smallest and biggest can survive

Bruh I had no idea what the teacher was talking about, but when I came here I understood. Thank you Teacher pet (Btw "Teachers pet" sounds like an insult tbh)

sooo...what happens to the chinook salmon males? are they either super large or super small or both???

@aphroditepantheon5984

8 жыл бұрын

+Henny Williamson Basically as a result of disruptive selection you are expected to find either very large or very small chinook salmon males, no intermediate ones, so yeah both I guess.

@pauladrewes8545

both. The small and big fish will be the most common and have a larger frequency. Maybe after many many years, the medium sized fish will completely die out

I need to know that beginning song

2 mins lecture gave me the "concept". But i was watching a 2 hour lecture of natural selection gave me nothing just a bunch of datas!

I'm doing this for 8th-grade science, anyone else?

Seems like bio 11 also learns the same thing

Totally nit-picky of a comment, but you can break Hardy Weinberg Equilibrium without Natural selection occurring (ex. migration, genetic drift, etc.)

thanks for a straight forward ass video. no need for a bunch of extra bs that doesn't get to the point.

ahaha.....so no kiss ?

Who else is here Bc of class

I understand nothing
