These videos are a lot more helpful than my textbook has been. Thank you for sharing these, and for teaching so well.
changing colours is very important in meiosis :)
Amazing explanation and thnx a lot btwn am in love with ur voice😊😊😊😊😊😊😉😉😉
bro what
your drawings are understandable to teach.
Very nice teaching
No one:
Sal: "Actually, let me use this magenta color here..."
😂❤We love you Sal
Thank you!
By the way, I freakin' love the way he says 'microtubules'.
Aweosome video......
Love the vid but what are you using to draw this I like it
the bottom gametes in telophase II are same but we were taught that all 4 gametes are different . please explain??
Do you have a flowchart with all he steps and stages?
Your voice is amazing.
why is it haploid in telophase 1 when there are still 2 pairs of chromosomes inside a cell (sry new to biology)
I have a question is the term microtubules = spindle fibers = meiotic spindles ?
.yeah
= mitotic spindle
Hi! Where phase did the centrosomes duplicated in meiosis 2?
shuanks I just finished watching meiosis I and II, ill come back after my exam tomorrow
I did bio exam pretty well, shuanks
metoo
what a fun lil voice
Best
Metaphase plate
is there a way to subscribe many times using one account?
first
wow betagi you should consider career as proffesor
I didn't see the need to show it for 2 different chromosomes!
But thanks for the video!
Does it matter where is the metaphase -horizontal / vertical
I too have the same question. In the video he does not address wether the chromosomes are aligned in pairs (like meiosis 1) or in single horizontal fashion. Can anyone shed light on this please?
I think I figured it out ) so the metaphase is plate can be also referred to as the equator of the earth - the equator is always perpendicular to both of the poles of the planet - the same is in the cell - the poles are centrosomes and the equatorial line is the metaphase plate where chromosomes line up rather horizontally or vertically
In meiosis 1 u have ur formation of tetrads or the connection of homologous chromosomes which exchange their material - that’s why they lined up in a pair form- in meiosis 2 they aren’t in pairs because spindle fibers in meiosis 1 attached to tetrads from both sides separating them out but we still have sister chromatids which have to separate apart so that’s why we have meiosis two - where they don’t form in tetrads anymore
No it doesnt its just a matter of display its the same thing it doesnt affect the process
