A Level Biology Revision "Cell Division by Meiosis".

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video we look at cell division by meiosis. First we explore how meiosis produces haploid gametes from a diploid cell. We then look at homologous chromosomes and how meiosis introduces genetic variation through the process of crossing-over.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.

Shaun I just wanted to say we have a pillow of your face in our school classroom

[@Freesciencelessons]

I don't even know how to respond to that. Thanks for letting me know. Say hi to your teacher and classmates from me.

My whole school knows you 🤣😂, u explain better than most of our teachers, you simply saved everyone's GCSEs and increased at least 2 grades for everyone in our triple group! Most of us passed with an 8 or 9 at our sciences, I can't thank you enough!

[@TbspOfRice]

did you say 8s and 9s
take me to your school

[@hazer660]

This man is literally a saving grace.

[@esotericmedic2841]

Very helpful video- I was just revising this topic and then I saw the upload. Thank you very much!

[@Freesciencelessons]

Thanks for the comment. I'm glad that the video helped.

[@abodismail2597]

@@Freesciencelessons we study this topic in our pre-clinical years of MBBS as well, so you saved me in my GCSEs,A levels and now in med school, Simply Thank you!

[@fpz3491]

The last video with Sir’s face, but I respect the decision. And hope you have a great week, thanks for your uploads.

[@user-xw1jf2dn3l]

Hands down he is the best science teacher that science has ever seen. Wallahi, i think you explains better than any of my science teacher at college. They are useless. I don't understand a word of them and i just come and watch you. How do you make it look so easy???

[@Maylaas_Library]

I watch your videos and I always end up getting A** on my tests!! Thank you so much for this.

[@jamesfarrell8541]

By far the best lesson I’ve seen on this u keep them short and sweet just like u shaun

[@TheDelicateDesigner06]

You will forever be a legend to us all

[@Sensitivityy]

i watched u when doing my gcse and now alevel u literally save my lifeee

[@jamie7707]

Thanks for this very helpful and clear video on meiosis. Is there any chance if you could upload videos on the different types of cells and their organelles please, so like the structure and function for each cell organelle in plant and animal cells as that’s also in the cells topic for aqa alevel biology. Thank you for producing these amazing videos!! 🔥🔥🔥

[@ay_3412]

i just finished my bio mock today and i wanted to say your video helped me alot

[@Dan-kz6dz]

THANKK YOU SO MUCH FOR ALL YOUR HARD WORK YOU DESERVE A KNIGHTHOOD

[@wonder_egg]

Cheers sir, this helps explain it a lot.

[@jamiemcconnell8864]

this is just perfect timing, thanks dude

[@thekidd1849]

thank you very much for your excellent videos real appreciate it keep making video sir

[@alexandra129]

Very clear and helpful thank you

[@P01SONx]

Hi! Wanted to let you know that at our school, when watching ur videos someone called out “i think he looks like a collin” so now everyone here knows u as collin! (even the teachers) and some kids have even started a “collin cult” so, sorry if this disturbed u😥

[@Freesciencelessons]

Not at all. Colin is a nice name. I'm actually called Shaun.

[@sciencealpha2843]

You are so underrated. It just saddens me :(

[@Doodles555]

Love u Shaun!

very cool, thank you 🧐

Did you make a video on stem cells for a level?

[@billhillier7075]

Ur a legend sir

[@johnrod5189]

what will you do after you have finished a level

[@md_rifat_chawdhury]

how many times cytoplasm divides in meiosis ?

[@instantdestruction411]

this dude is literally so famous in my school

[@kaelyn8705]

is this aqa or ocr?

[@darkninja383]

last live video 😭

[@matthiasfernandes5978]

thanks g

[@user-lv5wy4tz5s]

Is this a year 11 concept ?

[@samuelcomlay4239]

You said that the maternal and paternal chromosomes cross over, however i thought that meiosis only happened in the testes or ovaries and so cannot have a mother and father. Could you explain this please thanks😃

[@Freesciencelessons]

By maternal chromosome, I mean the chromosome derived from the person's mother. The paternal chromosome is derived from the person's father. Every person has 23 pairs of chromosomes in each cell and one of each of the pairs is maternal and one paternal (ie came from their mother and came from their father).

[@malcolm824]

another day of wanting to know this mans name

[@robbylane7996]

This was very helpful - robby2trappy

[@bucklandlover]

i have him as my pfp for a reason, guys a legend

[@rebeccamoore7519]

Really helpfull wheres the second part of the video pls

[@Freesciencelessons]

Thanks. You'll find it in the playlist "A Level Biology Cell Division".

[@aleehadilawer1507]

He is so good. Everyone subscribe to him now!😤😂

[@crazyking_sigma]

Thank you for the video, I understand this a lot more now. Also for your video on shapes of molecules the molecule with 6 bonding regions is called octahedral, I found an answe online saying it is due to the 3d shape having 8 faces, please would you be able to confirm if this is correct. Thanks again 👍

[@Freesciencelessons]

Hi and thanks for the comment. Yes that's correct, if you imagine a 3D octahedron, it has 8 faces.

[@jamesvlogsandmore9803]

Aight everyone here is doing last minute revision

[@adamspitfire]

this sounds more like gcse biology but a bit more advanced

[@macca6337]

crazy

[@shuuush1859]

i’m definitely not making it out of school.
