And no, everyone won't be the same because some people get mixtures of genes that result in them being unusual. It's just more likely you'll be more average than your parents. It's not for certain you will be. I have one sibling who is very short and one that is very tall. The rest of us are smack in between mom and dad. Averaged.

Statistically speaking, my husband and I had a 50/50 chance of producing a child wiht an IQ between ours, a 25% chance of producing one with a lower IQ than either of us and a 25% chance of producing a child with a higher IQ than each of us. We have one on each end and none in the middle, however, the avereage is closer to average.

Keep in mind that Einstein didn't have gifted children. If your theory were true, he should have.
Genes do not mix the way you are portraying it. If you have a gene for trait A and you husbands is little a. Your kids will express one or the other not some halfway point.

Additionally, every trait you are talking about is multigenetic. There is again no midpoint because no new genes are created, they are just rearranged. Ant rearrangement does not favor averages.

I'm one of six kids. Both of our parents had genius IQ's. Of the 6 of us, two have genius IQ's, two are well above average but below our parents and 2 are much closer to average than either of our parents. While two are as intelligent or perhaps more intelligent than our parents, 4 are not so the average is closer to average even though 1/3 of their kids are in the genius range.
Iq is not a purely inherited trait. Studies measuring effect of none heritable factors place it between 10-40%.

Please stop mangling genetics.

And as you said, averages apply to groups and then you try to present your family as representative. It is not.

Maybe some recessive genes in there?

So, If genes don't "mix" at some "half-way point" than how do you explain bi-racial people who are clearly lighter skinned than one parent and darker than the other? That would obviously be the genes of the whiter parent muting the effects of the genes of the darker parent?

If it was your version of average, you would not be able to distinguish whose nose, eyes, chin, mouth, hair, etc. that your daughter has. All traits would be a blend of both parents.

In some families all of the children look identical to one parent. In some families, some of the children look just like one parent and some look just like the other parent. Some have kids who, like yours, have traits from both sides. There is no blending. I know a family that has 5 children. One has red hair, one blond, one very dark brown, one strawberry blond, and one golden brown. The parents have dark brown and blondish hair.

I'm one of five. Our parents have blue eyes and hazel eyes. One of us has blue eyes, one green, one brown, one hazel, and one light brown. None with bluish hazel. Two look like my mother, and three look like my father. No blending, or we would all look alike.
Genes don't blend??????????????????????????????????????

How can my father's genes stay separate in me from my mother's genes?

I never heard that before.

?????????????????????????????????????????????????? ??????????????????????????????????

Ugly ducklings effects. Puberty expose the kids to hormones will change facial structures. Generally, the higher level of estrogen will give females wider eyes, smaller chins and bigger lips (and before you inject your daughter with estrogen during puberty to help her with her modeling career; please note that it will stunt her height as well). Whatever your family traits you have are still there. But hormones mess with them a bit. Also, when they learned to take care of themselves, either healthwise (which improves your survival rate and makes you a good candidate for passing on your genes) or grooming/primping wise (not looking like a crazy/mimicking facial features of highly fertile female with makeup), you're making yourself more attractive.

This is so stupid.

Most of your Top Models were incredibly plain children.

Having freakishly pronounced cheekbones and wide eyes can do that to a kid's face.

Myself - born to two good looking people, ugly as a hatful of spiders for the first 12 years of my life.

After that - well, I'm getting better as I age.

Having a baby face is awful when you're young, a blessing when you're past 30.

I'm not about to read five pages of posts, so chances are I'm about to repeat someone else's comments.

A lot of goodlooking people were NOT goodlooking children. Also, I have known a LOT of pretty children who grew up unremarkable-looking while plain to ugly ones became very attractive when they grew up.

And sometimes inheriting a mixture of the handsome parent's features don't seem to work together. The daughters of Bruce Willis and Demi Moore are good examples.
