Sex Chromosome Abnormalities 

I am a med student and you saved my exam of genetics, your lectures are awesome for understanding the basics so that i can study the details more easily

your lectures saved my time and get me through my exam . in no time , my head was blank and non receiving but your lecture are so awesome i could not stop watching ,,,, thank very much :-)

Most lectures never mention what the function of the Y chromosome are. But you did, letting us know that it produced all the attributes of maleness. Can give us more detailed lecture on X inactivation. Thank you for well produced lecture. Very helpful

Hi I am from Yemen , I love your lectures specially genetic You are a good teacher

Is that all the abnormalities? I mean, what happens if there is a person with XXX? And what happens if a person has XXXX or XXXY or XXYY? And what happens if a person has 0 in the egg and 2 in the sperm or vice versa? I know at the end, in the las example has 2, but if it YY, what happens? And what happens if the egg has 0 and the sperm 1, or vice versa? I love your explanation, that’s why I’m asking. So thanks.

Wooow awesome lectures, at first I was so confused but after washing your video, I got so much clarity

Great video, literally the best one I could find on RU-vid.

Have a test coming up in an hour. This was very helpful. Thank you.

Although this video is good. Like most videos. For the average laymen it can be difficult to follow. You should provide links to introductory videos just in case. Maybe draw the process out as your lecture. Seeing a whiteboard full of writing can be overwhelming to some.

Amazing lecture. I love ur style, u're a gift to teaching Ma sha Allah

Thank you very much.

How would you respond to people who say these genetic conditions are 'a third sex'.

I believe the XY is an Abonormality, kindly advice, why do we as man have Nipples that we have no use for. Isn't the XX Chromosome the orignal. Is is not true that everyhing start with the XX, if so where did the XY came from. I am just asking

You're the reason how I keep my 4.0!

good job.your lectures are much effective.

Did XYY type males forms barr bodies like females to compensate the double dose ? And how the make viable gametes ?

Sir ,could you please explain how 48 xxxy (klinefelter 2) occured?

Why can't I find any info on my 46 xx sry positive abnormality, years now trying to figure out what is different about me other than not being able to have children and my insanely low testosterone.

you should come teach our genetics doctors in TSMU

This should have been what Bill Nye talked about on his show.

Thank you for this Sir♥️

yeahh... they don't like being told they are an abnormality . that humans are, having for true, 6 sexes and is it possible to be an xy female without swyer's syndrome?

Nice one

Good lecture but too small to see 🤔

You are confusing sex and gender, but still wrong about it being binary.

What if sperm number 4 fertilised egg number 2? Would there be any abnormalities?

good job.your lectures are much effective.
