so does that mean that a few hundred years into the future americans will possibly have a faster metabolism and cure the obescity rates?

this is very resorcefull for my science paper

Read about the starkids.

Wow, I see plausible deny-ability in your near future. If I were to ground break such findings...one would tend to..... arm it against the obvious, indoctrinate it for the oblivious and understand it for the obnoxious. What do 269 random samples of present genome have to do any time based formula?

Where is these 2 species came from? Male & Female. Male in the living process, he will change the body shape, he will have anger, he looks at female, he like sport, he will wearing sport T-shirt, he needs sexual, all the Male in the process almost doing similiar things. For Female, she will love to care, she will likes to wear nicely, she will thinking to be pregnant, she will love to teaching the children, she likes to buy clothing, she will gossip with group of female, she will less sex during late age, all the Female almost doing the similiar things in the process of living. (We can talk about Gay & Lesbian, because they are from Male and Female from the first place, they come from some special thinking, environment changing, so to become different). So, why these 2 species contain the similiar on their journey of life? Why have this 2 only creature? Where are we came from? WHy some many centuries we still can train a monkey become human at all (but, we still imaging us came from water species to become monkey, to become human, all this just a thought?).

Where are we really come from?

I think that scientists and researchers should be spending their time on something that is actually useful. Look at all the problems we have today. Do something to try and help fix those. Creating a "Customize Your Baby Farm" is completely wrong and lacking in any kind of morals at all.

This presents another interesting topic. Cytoplasm is the liquid found within all cells, that suspends the cells organelles, which perform the processes nessecary to the complex life exhibited by eukaryotic organisms (organisms that have nuclei to carry genetic information.) Modern geneticists have recently discovered that these very organelles may have once been their own organisms, and are merely duplicates that now survive within us, coexistant and assimalate. The organelles perform many processes; ribosomes make proteins, mitochondria produce energy using cellular respiration, chloroplasts prodruce energy using photosynthesis, etc. These abilities are possible due to their unique genetic make-up. However, this make-up, much like the main genetic information found in the nucleus, can include genetic defects. When this happens, the basic foundation of the organism in which the defective organelle is compromised. When the foundation fails due to a mitochondrial defect, the organism is left without the nessecary energy to obtain sources of energy, replicate, replace, repair, or develope. Basically, the organism will starve for energy and nutrients. When this happens, the organism will die a painful and inevitable death.

The injection of a third parent's cytoplasm includes the organelles present in the original cell; if the organelles are without defect, and the new cell accepts them, the new organelles will function much like the original organelles would have. If and when the original organelles fail and die, the new organelles will continue to function as if nothing happened. The original organelles, now dead, would then be consumed by the lysosomes and used to build new nondefective organelles. And there's the wonder in it; with the new organelles having their own DNA (deoxyribonucleic acid, or genetic information), they can (with the help of the ribosomes) create duplicate versions of themselves, and when the cell grows large enough and begins mitosis (cell division), the duplicate versions of the organelles will pass on to the new cells, and then the cells after that. With the injection of these nondefective organelles pre-fertilization, every cell in the embryo will be corrected. Thus, the organism resulting from this embryo may be saved from death, or brought to life, by this remarkable procedure.

No, not nessecarily. Somatic genes are in fact inhertied from both parents, as evidenced by the somatic genes examined by the great Gregor Mendel when he cross-pollinated pea plants to get different colored pods, peas, and flowers; and different shaped pods and peas. What this author is referring to are how the somatic genes of humans are much more complex than "left or right." In human somatic genes, the combinations of singular genes on the chromosome affecting a particular trait actually create different results; this is why people that have black hair that mate may have a blonde child, or vice versa. The author means that the basic outcome of the genes are not inherited. The genes, however, are.

I think it is very sick for parents to want to design their child. We need to be working on helping to fight all these diseases,Yet, we want to come up with ways to decided how a child sould be before birth. beside parts of being a parent is to help your child grow.

I personally don't think genetics should be altered unless it's to help fight disease. I think that being able to choose how you think your baby should look, what color the eyes should be, height, gender...It's wrong. Just be happy with what God gave you. Now don't get me wrong, I'm NOT one of those Bible-huggers, I don't even go to church. But I do have a MORAL conscious. We shouldn't be able to order babies the way we order our fast food and vehicles.
