1. your fruit fly and flower drawings are wonderful 2. thank you so much for making these recap videos (both these and the normal unit ones) it’s SO HELPFUL to review before tests and just as a supplement to what i’m learning in class. You single-handedly got me through unit 5, and i’m looking forward to the rest of the unit recaps. thank you!!!
Hey I'm self studying AP bio this year, and I just wanted to ask what unit are you guys currently on In school so I know if Im on track, thank you for this video by the way. Super helpful.
I turn off my wifi while I'm recording because we've had some issues in the past where I get iMessages that pop up on my screen! During these units (especially Unit 6), it's easy to get caught up in the technical terms and the details about some of the more complicated processes, so when you're studying, I'd just say make sure you know the basics and you have an overview of how things like the different modes of inheritance, replication, transcription and translation work before you get into the specifics about them.
Thank you so much Mr. Poser. I was wondering if you could keep doing unit summaries like these? I find them extremely helpful especially as the ap exams are coming soon.
Hi Mr. Poser. At 10:30, you said that independent assortment occurs with the arrangement of chromosomes in metaphase 2, but if the homologous pairs are being arranged randomly in the side by side position before being split across into 2 haploid cells, wouldn't that be in metaphase 1 before anaphase 1 where the homologous pairs split, instead of metaphase 2?
Also at 11:40 you said that theres 2^23 possible arrangements of the chromosomes, but that probability refers to when there are 2 possible positions and 23 of these events, which I think is in metaphase 1 when the homologous pairs line up side by side. I'm a little bit confused about this, and I have a test coming up tomorrow afternoon and I know a lot of ap style questions on this topic specifically ask to identify meiosis stages based on information like this.
So yes, I must have misspoke about independent assortment. The alignment of homologous pairs occurs in metaphase I, not II. Independent assortment states that the inheritance of one chromosome does not affect the inheritance of another chromosome, and that homologous chromosomes can align themselves in any configuration. And yes, 2^23 possible arrangements of homologous pairs in human meiosis. For example, if there were only three homologous pairs, there would be 2^3 or 8 different arrangements of homologous chromosomes.
Hey so Im in my second semester of AP Bio and I have a test on unit 6 in 3 weeks. I have no knowledge of unit 2 3 4 and 5 because I didnt study at all last semester. which units do i need to study before starting unit 6? Out of unit 2 3 4 and 5 which units have concepts that are neccesary to know so that i can do well on unit 6? Please let me know how I should approach studying for this test and by the way your videos are amazing, I learnt unit 1 by taking notes on all your lesson videos.
So to be honest, if you're taking the AP Biology exam, you need all of them. I can't really pinpoint stuff you need to know because at the end of the semester, you do need to know everything from the course... I mean if your test is on Unit 6, prioritize that but there aren't really any shortcuts if you gotta eventually know everything.
I think I go over a pedigree question in one of my AP Biology Exam Prep videos (Visual Representations?) but if not, all pedigrees do is show patterns of inheritance (autosomal/sex-linked, dominant/recessive) from one generation to the next. Let me know if you need more explanation
Mr poser your are a true hero without your videos I have no idea how I would have survived ap bio thank you so so so much :)
I'm happy to have helped! :)

thank you!!!
I try really hard on my “art” 😅
I’m so glad I can help and that this works for you!
Thanks, ive learned units 1-5 in just a few days thanks to u!
Good luck today!
You're great and very helpful! You explained everything flawlessly.
Wow! Appreciate you saying this
just finished my AP bio exam tysm for everything!!!
My pleasure!
i love your videos, they have been so helpful. Thank you so much!
Of course! I'm glad to help.

We’re on topic 5.3/5.4 right now. A little more behind schedule than I’d like but that’s where we’re at
THANK YOU SO MUCH MR. POSER! our test is next wenesday and i always look forward to ur recaps! :D
Good luck!! You got this
Thank you for this video, clear and too the point 🙏🏾
Glad it was helpful!
Mr.Poser, fire video but u don't have wifi! Also I am having a test on unit 5 and 6 this week any advice?

Im glad you find them helpful! I’m almost done preparing unit 6. I will be doing 7 and 8 eventually!

@@poseknowsbio thank you! Are you doing the unit 6 recap anytime soon? It would really help

What about pedigree?

no cap you should go clean shaven a lot more you look hella clean. Sorry for going off topic.
One of the best comments I’ve ever gotten 😂
Glad you like the look 👍
