Thank you sir, you really deserve hundreds of thousands of subscribers.Hope you and your family are doing well.

This was so so useful! Exactly what I was confused about

[@MrExhambio]

No problem

[@joemichael9521]

im supposed to do cornell notes to this ?!

[@mandokabazo1826]

Do u teach physics sir? Also i love ur vids u have been my tutor for like 4 months so thank u

[@MrExhambio]

I’m afraid not. Thanks for your feedback, so glad you like the videos

[@birdie7344]

quite helpful!

Also big up my man mr t lewis

[@akshayaravi2360]

thanks a lot, but can i ask why plants are vulnerable to pests if they are genetically modified?

[@babyoil00]

Well if you're still here then here is the reason. Plants which have better characteristics ( therefore the genes coding for the characteristics) are chosen to be genetically modified. The explant ( the tissue taken from the plant to be genetically modiffied) is micropropagated and when it grows, it is micropropagated too. Over a few generations, the same genes are propagated and the plants with the less desirable characteristics( therefore the different alleles they have that code for the characteristics) start to decrease in number. Now when almost all plants contain the same alleles with less variation and diversity, if a disease or a pest that can attack the plant appears, it might end up quickly affecting all of the plants causing a massive loss. Sorry for the excess explanation, I am still a school student and dont know how to summarise it properly
