I am a male but, and this is where it gets interesting, i have never seen my dad. So i am 15 and i wonder where does your appearance come from? Which genes determine your height, hairyness ect? And what parent do they come from? cause my mom has no hair and i haven't ever seen my dad so who will i be like?
Plus does your voice come from your parents or is it individual? Does the baldness gene come from yur mom or dad? And what about the amont of melanin cause that effects your skin and hair and eye color? So what parent do you take after? My hopothesis will be if you are a male then you will look similar to your father because you are of the same sex.

Ok, I'm a bio student, so I really tried to give your question a good answer, but it's just not working! Genetics is a very complicated matter, and it takes a while to understand it.

This is a good site that I think may be able to answer some of your questions. It's predominantly about eye color, but it has to do with genetics in general, and I think it may help you.

I don't really take after either of my parents. In fact, I look nothing like them except for a few features here and there, but those similarities aren't even that obvious.

There's a lot of questions in there! Wow!

It's often accepted that baldness is maternal. That's excellent for me, considering that my father is bald and my mother still has a head of hair. [Smile]

That's an interesting hypothesis that you have. If that is the case, how would you explain the fact that I more closely resemble my father, as do my brothers, even though we have different mothers? Our baby pictures are nearly identical. It's kinda funny.

I phyisically resemble my father more, though I have some of my mother's finer personality traits. Like her fiery nature.

There's no evidence to support the idea that sons resemble their fathers more, or daughters take after their mothers more. Genetics isn't that simple. Baldness, for instance, can be inherited from either your mother or your father (sorry, DarkChild!! [Wink] ).

Basically, the traits you inherit from each parent are decided by chance. That's why, for instance, I look exactly like my father even though I'm female, but my voice is almost identical to my mother's and we have very similar personalities. It's just random.

oh ok i kinda assumed that you may more closely resemble one of your parents but thanx for the responses.

That's okay, Karybu. [Big Grin]

At least for me, if I did get my dad's genes on that, then I'd be going bald now. Which isn't happening.

Go thick hair!

To get an idea of how genetics works, google "Punnett Squares" and follow what they say. It really is totally and utterly random.

Many human characteristics are polygenic, meaning they are controlled by more than one gene. If you have one tall parent and one short parent, for simplicity's sake, we could say half your height genes code for 'tall', half code for 'short' and you end up at an in-between height. Skin color works much the same way. My siblings and I share almost the same skin color, which is in the middle between our light-skinned mother and dark-skinned father. In most cases, even a tall person may have a few 'short' genes. Depending on what the random combinations at sperm/egg formation and fertilization end up being, there can be a lot of variation even among siblings.

The sperm/ovum has only half the genetic material from a normal cell and there is some real mixing and matching during formation, so which half of the genetic material ends up in the final products is for practical purposes, completely random. Traits that may be genetically recessive (overpowered by other genes and therefore unseen) in the parents could still show up in the child, if the particular genetic combination at fertilization allows it. That way, you could end up with something that bears no resemblance at all to either parent. The inheritance of most characteristics has nothing to do with which parent they came from. Like everyone said before, it's random. [Big Grin]
