That is 34 yrs from now so these babies will need to start being born now in order for that to be true.

It could mean average as in the average of all different types. It just means whites won't be a big majority, non-white populations are already growing.
Okay, "light-skinned." The average skin tone of most Asian countries, when looked at composites similar to this one, have lighter skin than this one. So by 2050 darker skin tones will have caught up.
yea, i'd love to link but i heard that years ago at some biochemistry class, sorry. as for explaining, Y chromosome is smaller than x and it features few important genes. most of it it's crumbly trash. lots of fatal diseases (like blood clotting disorders) are encoded on Y chromosome and i think we were told something in the context of natural selection trying to dispose of it. something like that. surely not in 50 years, i was joking. :D if you have two copies of x, one might be faulty but the other covers for it. if you only have one, you're fucked. that's some sort of a fundamental flaw or whatever that would alledgedly erase itself by removal of chromosome Y. that's just a bedtime story, really. the reasons for it are probably way more fucking complicated and on a molecular level.
I am sorry, but that is quite untrue.
In April 2014, researchers at the Whitehead Institute for Biomedical Research concluded that the Y chromosome is in fact quite stable, and encodes for genotypes even outside of reproductive purposes. Additionally, the Y chromosome itself is used to trace paternal lineages beyond 2000 years ago (and allowing a man to discover from which haplogroup he is descended) remaining as a whole largely unchanged since then. It is stable and essential. Males as a sex will exist for millions of years to come.
It will change over a long period of time, true, but so will the X chromosome. That is merely a reality of evolution. The Y chromosome is not "disappearing".
No. Colour blindness and baldness, for example, are sex-linked recessive traits carried on the X chromosome (though baldness is also partly autosomal). Men inherit a carrier X chromosome from their mother and, because they have only one X chromosome, they are then diseased by it. The Y chromosome plays very few active roles in causing disease. If you do not believe me, please, I encourage you to read up on the subject.
i am shocked to see a) how uneducated i am despite getting education for roughly 15 years and b) how uneducated are the people who were supposed to educate me
apologies for whatever inaccurate information i might've shared.
hi! I don't want to be rude but I do think I should correct this so sorry but no it's not! I read this article and this is a real woman who is 19 and they used her photo as an example (among other photos of real people) to show how mixed the human race is getting (which is really cool!!)

But good point..
it's not going to disappear in 50 years but in a few thousand, anything can happen.

Support stem cell research!
LOL!
