Mr Andersen is so helpful, he is possibly the best teacher I've ever had. I just love how he has so many videos covering a large number of scientific concepts and that he explains everything in such an engaging and easy to understand manner. Thank you Mr Andersen, I owe you so much
i am taking a graduate level nursing course, and your videos are so helpful in recalling previously studied material that has long ago left my memory. thank you for sequencing all of your material in such a coherent and gripping fashion!
I have a science exam coming up and I always got haploid and diploid cells messed up, not anymore!!! Thank you so much I feel way better and think I'll do well on my exam!! Thanks again👏👏👏👌👌👍👍👍
It's not hard to remember the difference between haploid and diploid. Remember "di" means "two," therefore 'di'ploid cells have two sets of chromosomes.
very helpful. I had to stop writing last night because I knew what haploid was but not diploid. fresh start - I am ready to tackle this paper with the right info! thanks!
This video was very helpful, thank you! I tutor cell biology here at MSU and this provided me a great, simple way to describe it to my students. Bozeman Rocks!!
I had some science homework to do retaining to this and was very confused. Searched and found this and cleared up everything! Thank you very much and keep up the great work!
Congratulations Paul ! I'm a biology high school teacher in Brazil and I do enjoy your videos ! Make things really easy ! I'll try to use some of them in my classroom.
I love your videos. I'm a biology student at Marshall University and they're all great for reviewing and studying. I'm in genetics now and even if I know most of this its still a great refresher so thank you!
Excellent teaching! But I have a comment. Haploid can be defined by the number of chromosomes present in a gamete. Haploid may mean one set of chromosomes (n=x) in diploid organism (2n=2x) or two sets of chromosomes (n=2x) in tetraploid organisms (2n=4x).
Dad Snatcher meiosis only occurs in diploid cells to turn them into haploid ones. if you're already having a haploid cell, and meiosis reduces number of chromosomes to half, but a haploid cell already possesses half number, so in that case meiosis can't take place. but in that haploid cell, mitosis can take place because it doesn't have to change the number of chromosomes. in short, mitosis occurs in both, haploid and diploid cells while meiosis solely occurs in diploid cells.
I recently have a dna on ancestry can you show me a video of how we are not clones ( my sisters and I) how we can have more traces from our grandparents
4:13 - He says that adult human somatic cells have 23 chromosomes, but I thought adult humans have 46 chromosomes ... doesn't n refer to the amount of homologous PAIRS we have, not the # of chromosomes we have? meaning we have 23 homologous pairs, giving us 46 chromosomes (not 23 chromosomes)?
After anaphase I but before telophase and cytokinesis, cells are still diploid. After meiosis I and cytokinesis, two daughter cells are haploid because the total number of chromosomes is the same with that of gametes (23 chromosomes in human). A duplicated chromose with two sister chromatids after meiosis I is not two chromosomes but one chromomose.
Sir please answer my exam is near ... Suppose our cell has 46 paired chromosome after the S phase so I will split my doubt into mitosis and meiosis Mitosis -: 1) total number of chromosomes in a) Anaphase b) telophase 2) Total DNA content in a) Anaphase b) telophase Meiosis -: 1) Total number of chromosomes in a) Anaphase 1&2 b ) Telophase 1&2 2) Total DNA content in a) Anaphase 1&2 b) Telophase 1&2 Sir please answer me ,,, I m bit confuse in this all the answer should with respect toh out cells chromosome number like we have 23 paired chromosome in G1 Phase , sir hurry please answer
You said twice that diploid means you have two complete sets of chromosomes (at 2:26). A set is two...so to have two complete sets means we have four of each chromosomes 2 x 2. Why at telophase ! of meiosis and telophase of mitosis is the cell said to be haploid? Doesn't it have 2n (two copies of each chromosome ) diploid number of chromosomes because it has to divide again to get to haploid, right?
This topic has confused me all year until I watched this!
haha I commented this my sophomore yr in HS during AP Bio... now I'm in college bio, and I'm back to Mr. Anderson

I thought I was imagining Ron Weasley before clicking this video
lol me too
Well it is rupert isn't it?
Ikr I was like "this doesn't seem right" 😂
struggled on and off with diploid and haploid for years, thanks Mr. Andersen
I use Screenflow on my Mac. I have put together a video that shows my method. Google "educational screencast". Best of luck.
Out of all the science videos out there, I find yours the most clear and informative. Thank you!
Easy to understand, straightforward and to the point. This clears everything up, I can't thank you enough
Teaching is an art, and you are a picasso :)

@Michael Liu Still here bud
THANK YOU MISTER ANDERSON YOU ARE MY HERO
Great video. But you touched only briefly on the advantages of each ploidy. I wish you would speak more about that.
I find myself watching this channel about once a month.
Good video as usual :)
What confuses me is the pictures of diploid and haploid.
so helpful. What had i been learning for 2 years of ap biology course... i could have watch this video before I almost fail
MR. ANNERSONNN! WELCOME BACK, WE MISSED YOUUU!
i am loving ALL your videos. you are answering so many of my questions! thank you!
Your videos are always helpful, thank you.
Very good informative video Mr. Anderson, I'm somewhat hearing impaired and thus very thankful for the subtitles.
This was VERY helpful! I've struggled w/ diploid/haploid, and this is my 2nd time taking Genetics in college...Thank you!
This video saved my life, thank you
i learn so much from you than I do with uc berkeley's infamous Biology 1A....keep teaching!
i learn more from you than i learn in class :'D thank you
Thanks a lot Mr. Anderson! So clear and informative
your videos always clear things up for me! thank you!
dude your are the best at explaining this!
Amazing explanation! Thank you so much for clearing things up! I'm a huge fan of your videos..thank you so much!
This dude is the Bee's Knee's
Woah, this video is FANTASTIC!! Thank you!!!
fantastic videos! Mr Anderson your videos are so helpful.
Super helpful, as usual. Love your videos, thanks.
THANKS SOOOOO MUCH, THIS HELPED ME A LOT
Which UNIVERSITY do you teach in Prof.Paul?
Thank you sir it was a great and easy explanation
Is this Alton Brown? (with more hair?)
Lmao I thought so too!
Your videos are awesome!! Thanks for posting!!
it was helpful but the last bit about bacteria was confusing
Thank you soooo much for you videos
You're a life saver
THANKS YOU MADE MY DAY BOZEMAN!
Is this video copyrighted? Can it be used for educational purposes? Thanks.
I don't understand why cells are considered haploid after anaphase I in meiosis. It appears as though they are still diploid.
YOU ARE A LEGEND!
Excellent teaching! But I have a comment. Haploid can be defined by the number of chromosomes present in a gamete. Haploid may mean one set of chromosomes (n=x) in diploid organism (2n=2x) or two sets of chromosomes (n=2x) in tetraploid organisms (2n=4x).
Finally thank you
This video helped so much thank you omg
What are the 3 main points of the video?
This was a great explanation! Thank you so much!!!!!
TH-cam is the reason I am passing biology
Are all mitosis cells diploid, and all meiosis cells are haploid?
if you are talking about the final products of those processes, then yes.
Dad Snatcher meiosis only occurs in diploid cells to turn them into haploid ones. if you're already having a haploid cell, and meiosis reduces number of chromosomes to half, but a haploid cell already possesses half number, so in that case meiosis can't take place. but in that haploid cell, mitosis can take place because it doesn't have to change the number of chromosomes. in short, mitosis occurs in both, haploid and diploid cells while meiosis solely occurs in diploid cells.
Ya , of course
PLEASE PLEASE PLEASE do a video on plasmid mapping. It's so confusing :(
Please may you do a video on the Mesehlson Staahl experiment?
DUDE YOU ARE THE BEST, THANK YOOOOOOOOU SO MUCH
thanks so much for your videos, they're a lot of help :)
very helpful! thank you so much
You are great. Thank you.
"if you cant explain it simply, you dont understand it well enough''-einstein. great video
Thanks sir the video is seriously helpful
My High Schoolers Love u!!! Thanks!!!
Is there any way to discribe this as a reflection? I feel there is something very deep here...
In haploi cells 23 chromosomes are present . Are they present as a single chromosome like chlomatid or in pairs
My science teacher sucks, can you replace her?? You're the best! Thank you!
What did Greg do?
Fascinating, thank you ♥️🇨🇦🌏
I just loved this video ,thank u so much ..........
Can you put the vedio of internal growth of plant please

Who are you!!! You are really interesting in teaching, I hope you will be going on and keep this way, thank you..
3:28 so we have pairs of chromosomes, but they are not physically connected?
What program do u use to make the video?
wow 8 years old rare comment
Excellent video.
You are great! Thanks a lot..
My AP exam is in less than an hour thank you 😭😭😭
And how mitosis takes place in diploid cell in which chromosomes are in x form?
Thank you!!!!!so much easier now
This was fun!! thanks

A duplicated chromose with two sister chromatids after meiosis I is not two chromosomes but one chromomose.
Binary fission takes place in bacteria what about viruses? Are they haploid or diploid?
Sir please answer my exam is near ... Suppose our cell has 46 paired chromosome after the S phase so I will split my doubt into mitosis and meiosis
Mitosis -:
1) total number of chromosomes in
a) Anaphase
b) telophase
2) Total DNA content in
a) Anaphase
b) telophase
Meiosis -:
1) Total number of chromosomes in
a) Anaphase 1&2
b ) Telophase 1&2
2) Total DNA content in
a) Anaphase 1&2
b) Telophase 1&2
