genes

All of these are influenced by the interaction of your genes and the environment in which you were raised.

The study of how genes and environment interact to influence psychological activity is known as behavioral genetics

Who wants to be told that there are limitations to what you can achieve based on something that is beyond your control, such as your genes?

It is easy to accept that genes control physical characteristics such as sex, race and eye color

But can genes also determine whether people will get divorced, how smart they are, or what career they are likely to choose?

Increasingly, science indicates that genes lay the groundwork for many human traits

"There's no way on earth that genes from an alga should work inside an animal cell," says sidney pierce from the University of South Florida.

Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are.

It's pretty incredible how it has managed to hijack the genes of the algae on which it feeds.

The slugs can manufacture chlorophyll, the green pigment in plants that captures energy from sunlight, and hold these genes within their body.

The term kleptoplasty is used to describe the practice of using hiJacked genes to create nutrients from sunlight.

Their babies retain the ability to produce their own chlorophyll, though they can't generate energy from sunlight until they've eaten enough algae to steal the necessary genes, which they can't yet produce on their own.

They get all their nutritional needs met by the genes that they've hiJacked from the algae.

Not only the coloring genes but lots of other genes are getting mixed up, too.

Now they are trying to figure out what molecular signaling processes activate those seed-building genes in resurrection plants—and how to reproduce them in crops.

Today skin color is evolving the new mixtures of people coming together and having children with new mixtures of skin color genes.

Yudell said scientists need to get more specific with their language, perhaps using terms like "ancestry"or "population" that might more precisely reflect the relationship between humans and their genes, on both the individual and population level.

His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day.

A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed hold patents to two genes that help forecast a woman's risk of breast cancer.

But in March 2010 a judge ruled that genes were unpatentable.

Companies had won patents for isolated DNA for decades-by 2005 some 20% of human genes were patented.

firms are now studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug's efficacy.

For example, it is unclear whether the sequencing of a whole genome violates the patents of individual genes within it.

One of the remarkable findings of the study was that the similar genes seem to be evolving faster than other genes.

The study also found that the genes for smell were something shared in friends but not genes for immunity.

Though not biologically related, friends are as "related" as fourth cousins, sharing about 1% of genes.

Why this similarity exists in smell genes is difficult to explain, for now.
