How many times are your genes represented in the Gene pool.?

Question

I know each child you have has 1/2 of your DNA. Grandchildren 1/4. Can anybody tell what nieces and nephews count , what about aunts, Uncles and cousins?

Answer 1

It's such a vague answer because the majority of all of our genes are not expressed.  Cellular DNA is inherited by both parents, but only s*x linked genes could really be located in a family tree.  It also depends on whether the alleles are dominant or recessive as well.

On the other hand, mitochondrial DNA is only inherited from the mother.  So if you're female, your mitochondrial DNA is the EXACT same as your mother's, as is her mother's and so on and so forth.  Since I'm a guy, that mitochondrial DNA will not be passed on to my children, so in essence my mother's mitochondrial DNA is ending with me.  Weird huh?  Mitochondrial DNA is in the mitochondria, which is an organelle in cells.   Chromosomal DNA is what you're talking about though, and that question cannot be answered accurately without a lot of tests while sometimes guessing.

Answer 2

Honey, they did a test looking for gene similarity and they discovered that over 12 MILLION people can be traced to the liniage of Atila The Hun...

ONE man, all those years ago, has left his genetic pattern in over TWELVE MILLION PEOPLE...

That means that wherever your home land is... Mine is Germany... you are related to MILLIONS of people... and that doesn't count the family members that, like my great grandpa, moved to other continents and other parts of the world...

Who knows how many people you are related to! There is no way at all to tell!!

Answer 3

Aunts and uncles have half the DNA of your parents, who have half of your DNA, so they have 1/4 of your DNA.

Nieces and nephews have half the DNA of your siblings, who have half of your DNA, so they also have 1/4 of your DNA.

First cousins (the children of your uncle or aunt) have half the DNA of your uncle or aunt (who have 1/4 of your DNA), so they have 1/8 of your DNA.

Second cousins (e.g., the children of your great uncle or aunt) have half the DNA of your great uncle or aunt, who have half the DNA of your grandparent, who in turn has 1/4 of your DNA, so they have 1/2 x 1/2 x 1/4 = 1/16 of your DNA.

Likewise, great-grandparents share 1/8 of your DNA, great-great-grandparents share 1/16 of your DNA, and third cousins share 1/32 of your DNA, as do great-great-great-grandparents.
