Click here to view an animation that describes nondisjunction. Nondisjunction occurs when there is a mistake during mitosis or meiosis. What happens to the cells that are made through nondisjunction?

Thanks Leslie! This really helped us understand Meiosis better!

Thats what they all say...lol

This was really helpful! I was a bit confused about this even though we reviewed it in class but now i understand how meiosis works!!! Thanks Leslie!!!
ReplyDeleteThat really helped me understand meiosis better Leslie! And now I know why some genetic mutations in the number of chromosomes occur, because of nondisjunction.
ReplyDeleteThis helped alot! It's so weird/cool how in meiosis the chromosomes split in so many different ways to get four chromosomes in the end!

Mitosis is cool.
ReplyDeleteReally interesting and so much clearer after todays double period :)Thanks!
ReplyDeleteThis really helped me understand meiosis alittle more, though we went over it in class.B-) It's cool how even though meiosis and mitosis sound similar their processes are different. Science is cool that way.(and it's even cooler when Leslie Sardinas teaches it)

the animation really clears things up!
ReplyDeletethxs! :)
how does a cell know when its time to split and reproduce?
ReplyDeleteThis really helped me understand Meiosis better, thanks.

Wow, I found nondisjunction interesting.
ReplyDeleteI found out that you can get Down syndrome from nondisjunction.
This was really helpful. Thanks Leslie~
Same as Radhika, how do cells know when to duplicate AND reproduce or when to just simply split and reproduce?
ReplyDeleteAnd can't the cell just split? Why do they have to duplicate and then split? isnt it more complicated?

Cool thanks Leslie, that's really helpful.

oh ok so meiosis produces 4 haploid daughter cells that are genetically different. But mitosis produces 2 diploid daughter cells that are genetically the same. For meiosis it is first duplicated than divided and then divided again...?so it keeps dividing into halves? And then mitosis just divides into 2 daughter cells...right?

I was still a litte bit confused between mitosis and meiosis so this animation helped a lot.
ReplyDelete~Wendy
This helped a lot because I was confused about what the different phases of mieosis did, but now I understand.

Thans Leslie! This animation helped me understand nondisjunction a lot better. It also helped me review meiosis.

ReplyDeleteTo answer your question, a cell can just split, but then it wouldn't have 4 daughter haploid cells, it would only have 2.
I have a question. In the video crosing over occured the firt time. Isn't it the second?
ReplyDeleteThanks anyway
just looking at the picture helped me!
ReplyDeleteMeiosis is so similar to mitosis, but so different at the same time
ReplyDeleteLauren
i always get confused with meiosis and mitosis but now i know that meiosis makes 4 haploid gametes and mitosis makes 1 diploid body cell
ReplyDeletesophia m 7f
I barely knew the difference to meiosis and mitosis but this helped a bit
ReplyDeleteIt's awesome how those cells can spilt... Meiosis is amazing :D
