My sister has Down Syndrome. She can't speak, she has to be held by her hand so she can walk. Millie is the best sister that I ever had, even though she is 11 and i'm 15, i love her and i can't imagine a better sis. If you are mean to her, i'm not your friend.
non c'ho capito nulla
Trisomy 18 eny broblem aaaa
The best video i've seen for this topic.
It’s doesn’t go from 46 to two cells with 23 to four cells with 23. It goes from 46 to two cells
with 46 then to four cells with 23
I need to know more
4:21 "so there are a few ways that this can go DOWN" 😉😉😉
This is really hard for me
is it just me or does this guy sound kinda like zach from the try guys
thanks
Did he … just say "less cells"?
Twice???
I love this video… 😊😊
I hope my kids won’t be mentally retarded with Down syndrome or something. Why don’t people abort down syndrome kids before they are born. It’s just depressing letting kids with downs into this world.
Umm whaaaaa…..??
Respect to the homies with extra chromies
thanks
Amazing explaination thanks Osmosis
In Robertsonian translocation ,why sperm carries pair and in disjunction sperm carries only single chromosome?
So nicely explained
Thank you for the explanation of the Robertsonian translocation!
You lost me at the chromosome..
all those scientists went thru the trouble to figure these complex stuff out just for kids like us to blame them for making us study
I dontttt understanddddddddd
In terms of heart defects, he states between the two atria (producing an ejection systolic murmur) being most common ('usually') but note the most common is an AVSD, which produces a holosystolic of course, along with VSDs
Prevalence
AVSD: 29%
VSD: 21.5%
ASD: 19.9% (EJ murmur)
So you will most likely hear a holosystolic murmur
source for chd prevalence ; Benhaourech, CHD & down syndrome
so basically saying, find someone with 23 chromosome pairs
I understand nothing
Outstanding…….
I made it to min 6… then my brain melted out of my ears :S
if this guy was my clinical instructor, i would definitely pass my subjects with flying colors
Great video. As a teacher I would use more colors for the stuff. It would be easier to understand it. I had to stop it once to remember the Chromosom comes from the Sperm. But great video.
Confuseddd
I already graduated from HS 8 yrs ago and now I understand the explanation more clearly 😂 really. My teacher didn't know how to explain either. So got bad grade, but no regret.
0:35
Because consent is important above everything else🙂👍🏿
Is there a cure for Down syndrome
what if a none chromosome (22) and the sperm's chromosome is 24? Is that possible to make a baby that not got a down syndrome? because the total chromosome is still same with the normal one.
Amen 🙏👌💐🙇♂
why is it the most common trisomy? is there a genetic based answer?
If the down syndrome is normal in genetic test reports,then the baby is healthy,and can I relief that the baby do not have any other problems like,organs problems
