How Cells Decide Between X And Y Chromosomes? Explained

- How does a cell decide whether to become a mom-cell or a dad-cell? Scientists once thought it was completely random. But experiments with mice showed that an entire organ, an eye, for example, can be mostly mom-cells or mostly dad-cells. It’s not random! It’s a mystery how the cell decides.
Scientists know the X chromosome much better. It’s part of the system that determines whether we become male or female. If an egg inherits an X chromosome from both parents, it becomes female. If it gets an X from its mother and a Y from its father, it becomes male.
But the X chromosome remains mysterious.
For one thing, females shut down an X chromosome in every cell, leaving only one active. That’s a drastic step to take, given that the X chromosome has more than 1,000 genes.
In some cells, the father’s goes dormant, and in others, the mother’s does. While scientists have known about this so-called X-chromosome inactivation for more than five decades, they still know little about the rules it follows, or even how it evolved.
In the journal Neuron, a team of scientists has unveiled an unprecedented view of X-chromosome inactivation in the body. They found a remarkable complexity to the pattern in which the chromosomes were switched on and off.
At the same time, each copy of the X chromosome contains versions of genes not found on its partner. So having two X chromosomes gives females more genetic diversity than males, with their single X chromosome. Because of that, females have a genetic complexity that scientists are only starting to understand.

The video cuts out mid-sentence, right when it was starting to get interesting.
So sorry for that. CZcams has a duration limit of 1 minute for shorts. For the full video, please check out our Instagram page.
@@TheWorldOfScienceCoHey i am a dude I accidentally drank someone sperm will my chill have that someone dna Or anything related to that guy
Can u pls.share the complete video link
can't you make a full video on yt
@@TheWorldOfScienceCo
yeah, it was the juicy parts
The one that express itself is called DOMINANT and the other that not express itself is called recessive
Hope it helps you
Thank u for clear explanation
You content is most underrated I have even see although I watched a lot video of yours since i came to know about you randomly thanks to the CZcams algorithm
I appreciate that! Thank you so much ❤️
full vdo please link please 🙏🏻
Where is the full video link
Rat:i have mom cell
Girl rat:i have dad cell
Thanks to the team of World of Science 🙏
I always thought that I'm a Mom Cell and yes I'm absolutely right😊 Thanks for such a clear explanation!
A mom what?
شكراً انا طالب سادس علمي ولدينا الوراثة وقد أفادني هذا لتبسيط الدرس 🤍👍
بعد 98 يوم امتحاني للبكالوريا لذلك يجب أن ابذل قصارى جهدي 🥹💔
Glad this was helpful. Good luck for your exam ❤️
بالتوفيق إن شاء الله
Thanks for saying that there are other patterns instead of just xx and xy
Now they are canceling the word "chromosomes"
Proof?
Who is “they”

Can someone clear this up for me?
How can it be that temporary traits are passed down to their offspring without them changing the genome in sperm or eggs as dawkins refutes? How can he say hes not impressed if these genetic expressions are passed down short term, but not long term, while simultaneously refuting the idea that any changes within a lifespan due to environmental changes could be passed to the gonads?
If epigenetic changes can occur, and genetic changes to an individuals genome can occur within a lifespan, why is it so hard to believe these changes can be passed down? Why is it strictly random mutations that steer the ship rather than intent or environmental circumstances which dont kill the subject?
2nd part please
Where's the rest of this? Would love to watch the whole video please 🙂
Actually, CZcams has a duration limit of 1 minute. Please check out the full video here - instagram.com/reel/CmGQKdppALY/?igshid=YmMyMTA2M2Y=
@@TheWorldOfScienceCo thank you! There's another short I checked out but can't find the full length video here on youtube. Are the others on Instagram too ? This is so interesting, thanks for posting!!🙏🥰
Yes. Thankfully, Instagram has 90 seconds limit for the reels. So, there we have ample time to explain in detail.
Can you put the rest in a CZcams video?
And that inactivated x chromosome condensed and form structure called barr body in female cells
I have an extra one
Everybody gangsta till YY...
That’s kind of a real thing it’s called Jacob’s syndrome it’s where someone has “xyy” chromosomes and they should live a typical life.
It’s all about decision making .
Suppose mom gene is inactive and a y gene which is also inactive comes
Thank you 🙏 for informing that
Daca la sarcina gemelara cromozom y decide ca cei 2 feti sunt de sex masculin???
As we all know that after fertilisation of sperm with Ovum led to formation of single celled zygote but as you mentioned it's clearly impossible to say whether to whole cells of our body have a origin from mother or father but i want to explain you that sperm doesn't contains any cytoplasm in it during fertilisation and while ovum does that's why all the human cells have a complete origin from there mother
YY cromozome will create a Chad
You'd need two dad's for that to happen lol
@@tylerdurden3722😂😂😂😂😂
@@tylerdurden3722Super Chad 🗿. No woman would be able to resist (that's why is prohibited).
Anyway is interesting that only Men can create Men. Women + women can't create men. Men are indeed more rare.
@@tylerdurden3722there might be a possibility if a woman who is able to have children had a y chromosome for whatever reason and they bothered gave it a y chromosome, that’s like a very small chance tho, and even if that did happen, the child would probably have a higher chance of dieing
No but. Adam was first man he has XY not YY the God used his rib X to make first woman with XX Adam+Adam = Female
X and Y
How to chromosomes and dapliod?
Otherwise known as binary, or male and female
You need to edit for CZcams brother
The female decides how much Mitochondria is distributed to the zygote in order for the 2nd X to lose a leg and become a Y thus creating a male from the FE-male
what that the reason 😊
What if both the chromosomes are inactive
Will be both
Because the ignoring chromosome forms a bar particle, which helps determine the sex of the fetus
Maitosis
Why almost prophets are male and have a books
Chicken and rice
Boy have different XY
Ladies have same XX
I’m a dude with XX
@@RussianSpyNikolai Bro drunk too much vodka 💀
@@CryptoIgnition It’s real. I’m intersex, and Identify as a guy. My chromosomes are XX making me a dude with XX
@@RussianSpyNikolai Ok, sorry for offending you
@@RussianSpyNikolai De La Chapelle Syndrome. You have the SRY gene on one of those X chromosomes.

For the rainbow community, how their chromosomes looks like?
