Title: Inherited genetic traits
Post by: Sylviaann on Friday 23 February 07 19:22 GMT (UK)
According to Gene Detectives we can inherit a lot of "interesting" traits

Can you tap your head and rub your tummy at the same time?
Can you make your nostrils flare?
Can you curl your tongue or touch your nose with your tongue?
When you clasp your hands is your right thumb on top, or your left one?

These are some of the inherited traits.

I can lift one eybrow, flare my nostrels and tap and rub. 
When I clasp my hands my left thumb is on top.  Apparently only 25% of the population does this.

I cannot curl my tongue.

Pity there is no-one left for me to ask if any of this is inherited but maybe you can check out your  family. 

By the way my son-in-law can wiggle his ears.

So can I and my brother, and my father before us.  My brother's two children can also, and there are the first signs that my daughter will too.  We are unsure whether this all came from my father's mother or father.

Sylviaann,

Maybe you are related to me - when I cross my hands my left thumb goes on top too!

However, it could mean that I'm not related to my parents as both of them cross right thumb over left which feels really weird to me.....

Hmmmm......

I remember a class experiment in Biology (mid 1980s)

A percentage of the class could roll their tongues and some couldn't.

Also we were given a droplet of a liquid to taste, I couldn't taste anything but some of the class were spitting it out as if it tasted of Marmite ;)

The lesson was all about genes - I've no idea what the liquid was, perhaps a RootsChat biologist can help ??? ;)

As I understand it, many of these traits are to do with dominant or recessive genes, like hair colour, eye colour, etc.

Fair/blonde hair and blue/grey/hazel eyes are recessive traits (like my father). If both parents carry the recessive gene, then the children will also.

If only one parent carries the gene, then all (some?) of the children will have the dominant traits of dark hair and brown eyes (like my mother).

And now I've confused myself. My three siblings have dark hair and brown eyes. I have fair/blonde hair and grey/blue eyes ... and I can wiggle my ears, raise either eyebrow independently, flair my nostrils and curl my tongue, and my left thumb is uppermost when clasping hands.

Uh ... mother? No! I don't believe it!  :D :D

I can do the tongue rolling thing.

My family all seem to have the same physical traits - black or dark brown hair with blue eyes.

My daughter can wiggle her ears,  and so could her great maternal grandfather

My other daughter can touch her nose with the tip of her tounge, and so could her maternal grandmother

Whereas me - I can't do either...

Can't wiggle my ears but I can dislocate my thumbs, as can my youngest son  ;D, no one else in our family can do this, makes my hubby feel ill when we do it  ;D

I've got one thumb dislocator daughter (ugh !)

Me ... the hand clasp thing ... I put left thumb over right thumb AND right fore-finger, then they go left fore-finger, right, left, etc... so I have two digits on right hand together under left thumb ... (heck, a picture is worth a thousand words they say !)

I can tongue roll, raise eye-brows independently, rub tummy whilst patting head, and the one they quoted on the site Guy listed on the Gene Detectives thread, about putting one arm over shoulder, the other under and round the back, to clasp hands behind back ... I can do !

Maybe this is what they call womens ability to multi-task ?    ;D ;D ;D

A friend has just asked me if there is anyone who can do what she and her son can do ... which is to close off the top/inside of her nose ?  So if you jump into a pool, for e.g., the water doesn't go up your nose ?  And useful against bad smells !   She thinks its closing the back of her soft palette ...

My Dad could wiggle his nose like Samantha the witch but I can't ...drats!  ::)
I can do the eyebrow thing and have dominant left thumb. The people who intrigue me are those that can actually "click" their thumbs.

Earlobes or the lack of them is also another trait

Two brown eyed people can have a blue eyed child
if both parents have the recessive gene (blue eyed)
BUT if one parent has both brown and BROWN
genes this will not result in a Blue eyed child.

One daughter can touch her nose with tongue - like my m-i-law!  She also has a double bit in her ear lobe - as did my uncle!

Things like eye colour aren't entirely genetic.  I know someone whose eye colour changed!

Eye colour is also linked to hair colour (although not linked to red hair) as the genes are very close to each other, which makes it far less likely that the father's chromosome and the mother's chromosome which swap in between those genes.

Also, contrary to popular belief, red hair is a separate gene to blonde/brown hair.

I have red hair, so did my great grandfather on my mother's side but I'm not entirely sure where it came from on my dad's side.

Me and hubby - both dark haired - him with green eyes and me with hazel eyes - our eldest has brown hair with dark brown eyes, our middle has dark brown with green eyes, and our youngest has very light brown hair with blue eyes - not sure where he comes from!

I can roll my tongue, raise my left eyebrow only, I have a loose "disclocated" thumb on each hand, I can do the Star Trek sign, and embarrassingly can touch my nose with my tongue!!!  I was always told I could only do that because I talked too much!  :)

When putting our hands together my daughter has her left thumb on top - whereas me and hubby have our right thumbs at the top.
