It's just a lot of copies of the same information. Not very efficient.

[–] Dadifer@lemmy.world 32 points 9 hours ago (1 children)

The dna sequence of each sperm is actually unique, and are thus not considered part of your body according to your immune system. This is why your testes are "immune-privileged", meaning your white blood cells are not allowed in there.

[–] Diplomjodler3@lemmy.world 33 points 9 hours ago (1 children)

So not just inefficient but also insecure? Who designed this crap?

[–] Dadifer@lemmy.world 18 points 9 hours ago (1 children)

Sexual reproduction is designed for variation. You can reduce it with a large amount of inbreeding. Your family, for example.

My mom, my dad, my aunt and my uncle are going to beat you up! The two of them are really strong!

They're just trying to get a point across.

Top Redundancy

It's not even. The data integrity algorithm is really kind of crap.

[–] EvilFonzy@lemmy.world 39 points 9 hours ago

That's why I always call it a packet storm. "Girl, I'm about to DDOS that booty."

[–] ooterness@lemmy.world 31 points 7 hours ago (3 children)

This calculation is off by an order of magnitude.

The human genome has about 3.1 billion base pairs. Each sperm has half of that. Ignoring epigenetics, each base pair has four options (A/T/C/G), so it can be represented by two bits each.

All told, that's 3.1 gigabits = 388 megabytes per gamete.

[–] dharmacurious@slrpnk.net 9 points 5 hours ago (1 children)

So what would the total amount of information in an average ejaculation be? Dumb it down for me, please? Lol

[–] LSNLDN@slrpnk.net 3 points 1 hour ago

Surely after some lossless compression this could be improved drastically

[–] io@piefed.blahaj.zone 1 points 1 hour ago

am i dumb or shouldn't it be 2 times 3.1 billion bits, so 6.2 gigabits according to what you said

[–] Track_Shovel@slrpnk.net 22 points 8 hours ago

If you assume an average ejaculation distance of 9 inches and a nominal speed of 15 mph (this is apparently surprisingly well studied) - you get a data transfer rate of 46,500 TB/s.

I once joked I could jizz faster than my shitty internet connection. Guess I was right

This is why a big...hard...drive is important.

[–] kibiz0r@midwest.social 4 points 7 hours ago

More buffer for the git pushin’

[–] Digit@lemmy.wtf 1 points 40 minutes ago

Doing a backup of some of my 18TB hard drive today.

This thread gets me thinking about that in new terms.

Not even enough space left on it for a tenth of a load.

And I thought 18TB was big when I bought it.

[–] HowAbt2day@futurology.today 5 points 7 hours ago (1 children)

Crazy to imagine that some Tylenol can corrupt so much data.

[–] grue@lemmy.world 4 points 6 hours ago

Yep, literally crazy.

[–] faizalr@piefed.social 4 points 9 hours ago (1 children)

How do they calculate that?

[–] albbi@piefed.ca 4 points 8 hours ago (3 children)

Each DNA base can be represented in 4 bits because there's only 4 values: A, T, G or C. (This is a simplification because of epigenetic base modifications, but works for now). So just take the length of DNA and multiply by 4 for the amount of bits the data represents. You do have to add up the lengths of all the chromosomes considering that sperm only have one copy of each chromosome, not two. Also factor in that there is no mitochondria in sperm. Lastly, about half of the sperm will be carrying an X and half will be carrying a Y chromosome so just take the length of the (X + Y) / 2 for the sex chromosome. Now just multiply by the amount of sperm in an average ejaculation and you'll get a good estimate.

[–] ooterness@lemmy.world 9 points 7 hours ago

Each base-pair requires two bits, not four. Picking an arbitrary convention: 00 = A, 01 = T, 10 = G, 11 = C.

[–] kibiz0r@midwest.social 5 points 7 hours ago

To represent 4 values, you only need 2 bits

  • 00
  • 01
  • 10
  • 11

How do they ejaculate that?

There are websites to help with that.

Does he have to? In every single thread?

[–] Formfiller@lemmy.world 1 points 3 hours ago

Sorry but he’s got a thirst

[–] Digit@lemmy.wtf 1 points 43 minutes ago

I don't wanna think about where his sperm has been.

Wouldn't quaternary storage need a different naming scheme?

[–] Kyrgizion@lemmy.world 1 points 7 hours ago

Pff I'd be happy to reach a megabit at my age.

Here's a 75mb joke:

There were 2 sperm, swimming along.

One says to the other one:

"We've been swimming for ages. How long until the egg yet?"

The other replies:

"The egg!? Oh. It's not for miles yet. We've only just passed the tonsils."

Edit:

This calculation is off by an order of magnitude.

The human genome has about 3.1 billion base pairs. Each sperm has half of that. Ignoring epigenetics, each base pair has four options (A/T/C/G), so it can be represented by two bits each.

All told, that’s 3.1 gigabits = 388 megabytes per gamete.

Oh, in that case then, I guess that's a 776mb joke.

[–] mdk@feddit.org 0 points 6 hours ago* (last edited 5 hours ago) (1 children)

Not that much information, but a lot of redundancy. Every sperm carries the same X or Y-Chromosome. So every sperm contains the same information as half of the other sperm. Or did I miss something?

Thank you, didn't know that
