eye color for a eurasian?

Question

is it true that a PURE asian mom/dad(for example, 100% chinese) and a white, blue-eyed mom/dad cannot produce a blue-eyed baby?

i heard that for there to be any chance of a blue eyed baby, the asian parent would have to have some white blood already, otherwise; they do not have a recessive gene at all, and therefore would never be able to make the bb gene pair with the white person.

Answer 1

yes it is true...you can use the punnet square to decide whether their child will be blue-eyed.

the asian parent must have the recessive gene for blue eyes acquired from an ancestor. if the asian parent has brown eyes but one of ancestors has blue eyes, there is a 25% chance that the child will have blue eyes. If the asian parent does not have the recessive gene, there is no way for the child to have blue eyes..BUT the child of THEIR child can have a kid with blue eyes if the other parent also has the recessive gene. because both carry the recessive gene for blue eyes even if they themselves don't have blue eyes

i know this is a lot but look up punnet squares on 'google' or something and it'll be crystal clear

: D good luck

Answer 2

Depending of where in Asia they are from.There are many asian communities,specially in the center of it that had interbred with caucasians since the year 5,000 B.C so they carry the genes even if not shown since generations.Slave trade made it the most possible to have spread it further into asian countries.Even just a few hundred,their descendants today would affect millions of "common" looking asians.Just from roman trade during their Empire subsaharan genes are found among very white looking europeans without a clue of any african ***** in their villages -or kingdom-for centuries.
The truth is that whenever a pale europoid or pale asian have breeding with a dark african or asian,the darker trait would be the safest genetic response as it is the ancestral common form from the Human race crib-lands.But as paler to the norths was an addapting specialization to light,this in itself is not lost in the box of genes but is recorded even if "dormant".But even ***** africans,can result wearing blue eyes on "produce" of some gene,from the parents. Chances,percents maybe less,but I have seen a black couple with two green eyed boys and the third even red-blond.Against odds?Sometimes,maybe the less,recessive takes over as the only "healthy'gene.Some races have inbreed between blue eyes so often as to make disappear their own brown eyed weaker members,making it "dominant"trait.But even they today are exposed to new members from the original lands,in their own until recent isolated Earth regions.
Have seen blue/green/gray eyed orientals in Mongolia,Korea,or Siberian elements (not the product of russian or scyth/iranian admixture known),and even blond among some chinese(!). And on blood research,testing positively related to their more "average looking" neighbors and family.
More seriously traced,it has been observed the blue-light eyed condition in african apes,and the macaques of Okkaido in N.Japan are well known as very"caucasian"looking.Even dogs and other animals show the eye pigment variation.
It is believed that all in the Human species carried the trait originally from Africa itself,even the one for baldness! as some male monkeys do...
However,not all the races took need of the blue-light eyed gene,and even if with it,random combination or/and the forces of survival -never again so demanding as Last Glacial Era- don't paramount for it to come out but as frequent as a mutation self.

Answer 3

Laurie is correct, the blue eyed thing is a recessive gene, thus can only be passed on unless it meets up with another recessive gene, then it shows up.

The only way this is possible is if somewhere along the line there was a blue eyed gene somewhere. ie. an ancestor met up with an european (whether she wanted to or not...)

PS. the other way, which is highly unlikely is if you have an albino child. They have no pigment at all so their eyes are blue-ish pinky...

Answer 4

Blue eyes is recessive. If you have a brown eyed parent, they would have to carry blue eyes in order for a child to inherit it.

Answer 5

Light color eyes are recessive, but there's more than one gene to determine eye color.
