16-10 Cross Over & Independent/Random Assortment in Meiosis (Cambridge AS A Level Biology, 9700)
มุมมอง 99921 วันที่ผ่านมา
2 important processes in meiosis helps to produce genetically different gametes. 1. 4:50 Cross-over during Prophase 1. When synapsis happens, the homologous chromosomes pair up, causing the chromatids to overlap and allow the exchange of genetic material at the chiasma (point of overlap). This allows for new allele combinations to be made. 2. 9:25 Independent/Random Assortment in Metaphase 2. T...

i gotta comment i love the PRODUCE MORE ATP!! made my night
if you are an otter teacher are we otter students???🤩
Don't ******* Panic!
i love your jokes sir. i love how u teach. rly fun, i watch your videos on my tv when im free 😂😂
Sirrrrr please pick up the pace it’s December already 😢. We still need a Chromotography video in photosynthesis and three more chaptersssssss. Which might be very long tooooooooooo.
Sir can you please make the syllabus complete till April cause we have Cambridge exams coming up in May so please it would be a great favor of yours❤
ur such a cool teacher cuz aint no way im understanding literally everything after i heard "bitchslap the heart"😭😭 THANK YOU❤
tysm for this 🙏
gonna be done w photosynthesis today yippie
<3
rhankuuu
Your videos are very helpful and I’ve read this physiology before and I knew a good bit but it was explained so well I learnt new things and expanded my knowledge
i swear this guy makes bio so easy
ikrrr
Sir can you please share notes of first 6 chapter i will be very thankful to you
@OtterBioTutor, did you do the chi-squared test video?
Ur SOO cool!!!!
Removing of plants cause of pollution😊
i love this channel it makes me so happy to watch these 🤗
Fr
sir can you please link these note in discription as it will be alot more easy
Thank you so much for the work you do. May you extremely be blessed.
Otter When did you give your a levels and what grades did you get?
thx thx thx thx uuuuuuu soo much 😭😭🥹🥹💖💖💖💖but can u pls upload the vid for chi square test pls
No bio teacher can match your level⭐️
sir can u explain meaning of *secondary messenger*? this term is used like everywheree
May Allah bless you with everything dear sir!. Just a small q too, when will the course be completed?
oh my god its finally over
bruh does this topic not end? What is this torture?
Ah! Awesome just awesome MA Tyy
Love you
sir i cant find the meselson stahl experiment anywhere in this playlist isnt it included in the syllabus?
Great explanation of all the topics 👏 Thanks a lot. But won't we do the chi Square?
you're so underrated. you're my fav bio youtuber now haha, thank you sm!
agreed
On which topic is this i’m new to your channel and want to start learning with you !!
It's part of chap 16: Inheritance

Thanks a lot for the amazing video sir. Your explanations are quite clear and easy to understand ❤ Could you please specify which of your videos are part of 6.1 Structure of Nucleic Acids and Replication of DNA, it would be great help
Thank you so much for these amazing and interesting videos. I’m doing A2 biology right now and your explanations are really good. Can’t thank you enough. Also, like someone said, thank you so much for making these videos free and accessible for everyone. Really appreciated. I wanted to ask, is there any sort of document or anything with the notes that you write and draw during these lessons videos? Thank you so much again.
0:46 at this point what isn't highly complicated 🥲
We have to do Chi Square as wellllll
Thank you so much for this amazing explanation ❤❤
I want to stay in AS level.. 😰
@@Zara-h5p 😖
You are an amazing teacher..you deserve millions of views. ❤
thank you for making it way easier, if anyone knows such yt channels which can help me with as level phy and chem pls lmk!!
can you make videos for 2026 syll too pls....just address the changes in syll content uf there is any!
