this is the simplest genetic model, though

it gets much more complicated

If the entire world mixed, do you think blue eyes would still exist?

yes

For awhile

they would be more rare

Ew furries

As time goes on they would become rarer

but the frequency of the gene would theoretically be the same

what happens to the frequency depends on who has more kids

We know that already

then the frequency would probably go down, based on current trends

But you can’t be certain right. I mean my brothers only have a 50% chance of carrying the gene, if they married someone with brown eyes and no recessive blue eyed gene, their offspring would only have a 25% chance of carrying the blue eyed gene? It keeps diminishing like this?

can't be certain about what?

Yes genius

Also there are like multiple genes tha code for eye color

Like green eyes are somewhere in between

if the mating was random and no type of person had more kids than any other type, the frequency of the gene would remain the same but you would see fewer blue eyes because it is recessive

@TheUserNameofPeace as per your advice, i got a shedload of sardines today

because the frequency is calculated simply by counting the genes, not the displayed phenotypes

and since the genes are still in the population, you would still occasionally get both the same in one person

But if my brothers have a 50% chance that the blue eyed gene has been eliminated from them, and their kids have a 75% chance it’s been eliminated from them (if they marry someone with two brown eyed genes), eventually the gene could be eliminated totally? It comes down to chance

Oi oi aussie m8

your brothers have a 25% of no blue eye gene

if your parents have 100 kids, about 25 will have blue eyes, 50 will have brown eyes but have one of each genes, and 25 would have only brown eye genes

but again, the disclaimer that eye color genetics is a bit more complicated than thsi

look at this article

Two blue eyed parents will always have a blue eyed child?

if it is a single gene recessive trait, then yes

unless they have a mutation

which is extremely rare

Tfw you have blue SNPs
