fascinating twins - anyone interested in genetics

DansMom wrote: This article is fascinating! The odds of a two biracial parents having twins so visibly differentiated is one million to one. I love genetics---if I had had any scientific ability early on, I would gone into gene mapping. Aren't these girls gorgeous sisters?

coasterqueen replied: OMG, how fascinating, you are right! So the one baby is black, not mixed? Wow, I'm speechless. They are both gorgeous too.

mckayleesmom replied: I have seen this on a show once...not with twins. This man brought his wife on a talk show because he didn't believe that their son was his. He was black and she was white. The little boy was bleach blonde and was white skinned. The results came back and he WAS the father. He just had most of her genetics.

jem0622 replied: My mother was telling me about this last night and the first thing out of my mouth was 'she popped two eggs'. LOL. Very unique and they are just lovely!

amynicole21 replied: That is very cool! We had a similar thing happen with a friend's sister. She had one white twin and one black... though she was, shall we say "promiscuous" and had been with both a black man and a white man in the same few days which explained THAT one

5littleladies replied: Wow-that is incredible! They are both beautiful girls!

J-rod replied: wow amazing.

is she really tanned or of some other decent than caucasion?


also i have heard...a really strange one..that can happen. 2 white parents having a black baby. if the genes are in the familly....its a long shot but i have read about it before.

mckayleesmom replied:
It said that the mom was mixed too.

Just goes to show brown eyes are not dominant; my Mother learned that 40+ years ago. My father has blue eyes with dark hair and my mother's eyes are brown with dark hair. They had 5 blue-eyed blondes!

C&K*s Mommie replied: As the mother of bi-racial children I love to see the results of the what DNA can do with children born to two different races of parents. The kids are gorgeous , and when the parents teach their girls that they are unique, they will have an extra meaning to the "unique" word.

J-rod replied:
sorry...didnt have the time....or patience... to read it all

~*Just Me*~ replied: Their fraternal, right, not identical? Otherwise they would look exactly the same? Still very interesting !

C&K*s Mommie replied: I do believe you are right, since they are not identical I suppose they fall into the fraternal catergory.

MommyToAshley replied: WOW... how fascinating. They are beautiful girls.

I'm like you and genetics fascinates me. I read some recent medical articles about DNA and twins that I'll share. Has nothing to do with this story, just found it interesting:

Did you know a person can have two different sets of DNA? A recent breakthrough discovered this. It all came from a paternity case in which DNA samples were taken from the same person and the person had different sets of DNA. The theory is that the person had a twin in utero that didn't form and was "absorbed" into the surviving twin.

And, there's a theory that left-hended people are "mirror" twins. I always thought that there was just two types of twins. But, there are actually many different types of twins, one of which being mirror twins in which everthing in the twin is the mirror opposite of the other twin (including the organs). Usually the mirror twin doesn't survive but there have been a few cases where they do... they recently had a case on tv where the twin had his heart on the left side of his body. Well, the theory is that left handed people actually had a mirror twin. I am not sure if I believe that there is enough evidence to jump to this conclusion, but it''s interesting just the same.

Thansk for the article... it was interesting.

Wrong. Brown eyes ARE dominant. The genes can skip generations, up to 5 generations back I believe.
I'll explain:

If say, for example, your mother's grandfather had blue eyes. His wife had brown eyes. He gives, say, your mother's father his blue gene, and the brown gene from the mom, the brown gene wins, but the blue gene is still there.

So - your mother's father (who has a brown gene and a blue gene) marries your mother's mother - who has 2 brown genes, and they have a child - your mother. Say your mother's father passes on his recessive blue gene - and your mother's mother passes on her brown gene - hence your mother has brown eyes, but she still has the recessive blue gene.

Now, your mother marries your dad. You mother has a recessive blue gene, and a brown gene. Your dad has blue eyes - meaning he cannot possibly have a brown gene. Absolutely imposible. Therefore, your dad HAD to have passed on the blue gene, and your mother HAD to have passed on her blue gene - making blue-eyed babies. It's a 1/4 chance.

Now replace the blue eye color with blonde hair, and replace brown eye color with dark hair - it explains the hair color. Your parents got really really lucky with the odds.

That's genetics baby!

(fwiw - I took microbiology, biotechnology and genetics in high school.... i would have continued had i not gotten a gov'y job and not gone back to school. I'm a total science nerd )

ETA - kudos if you understood what I said.

kimberley replied: they are both adorable! i love genetics too.

luvmykids replied:
Are you saying people with brown eyes can have other genes, but people with other colored eyes cannot have the brown gene? Just wondered if I understood that part.

ediep replied:
yes, you are right

although Rocky, genes can't "skip generations" only physical traits can, sorry....I am not only a sciece nerd, i am a science teacher

luvmykids replied: Now I know why I didn't do anything scientific! It's incredible but I admit I had to reread it. Beautiful though!

Boys r us replied: Those babies are stunningly beautiful....Sounds like Mother nature was working over time to achieve these one in a million odds!

punkeemunkee'smom replied: Beautiful girls!

HI Nicole!!! I have missed you!

Cece00 replied: ZEN is right, you must have 2 recessive genes to get a light colored eyed baby....

i'm brown eyed but my dad has blue & mom has brown...my boys dad had blue & we had one blue eyed/blonde & one brown/brown

same thing with my current hubby, he has blue & I have brown & our daughter is blue eyed.

Two brown eyed ppl can also have a blue eyed/green eyed child if they both carry a recessive gene for it.

Brown hair is also dominant. Blonde & red are recessive.

I love genetics/science, too. I was a Microbiology/Pre-Med major & wanted to go into genetics.

Very interesting article. Odd, though, that the 'white' girl doesnt look like either of them, to me. But the other little girl looks just like dad.

My3LilMonkeys replied: Rocky and all of the others are absolutely right! Along the same lines, DH and I both have blue eyes, so unless there is a gene even more recessive than blue (I only did HS genetics so we only covered brown & blue - no green or hazel or etc.) there is no way we will ever produce kids that don't have blue eyes!


But they are both gorgeous children!

Hillbilly Housewife replied:
Sorry - maybe i said it wrong - i mean that just because your mom, grandmother, etc etc... has blue eyes, it doesn't mean that the recessive gene doesn't show up in all of them... but that they may all have brown eyes and because they have the recessive blue gene, a baby eventually can show up with blue eyes if the other parent has that recessive gene as well and both parents pass on the recessive blue gene, even if everone else has brown eyes.

That's what I meant by skip a genration, my bad.

ediep replied:
I know I know.... I was just showing you that I am a bigger nerd!!

Just kidding with ya

you also have teaching experience... i haven't taken a class in several years!!
