No. Only certain genes are active at the same time. When they are not active, they are turned off.

Why 2 children have the same parents dont have the same chromosomes and genes?
There are millions of possibilities for combinations of the two parents' genes. They don't combine the same way each time. People carry recessive genes for traits they don't show, so each egg or sperm has its own unique combination of genes.
Why do organisms turn on and off genes?
Each cell in out body contains all the genetic information of that organism. However, not all the information is needed. For example, a muscle cell only needs information about being a muscle cell so it would turn off information/ genes that it does not need. Also, some genes can be turned on and off when needed. For example, some bacteria can use lactose but lactose is not always present in the environment. Instead of wasting time making lactose enzymes, the bacteria would keep the gene turned off until it was needed.
What is called when two or more organisms seek the same resource at the same time?
They have a party
What critical things genes were known to do?
A: first,genes had to carry information from one generation to the next; B: second, they had to put that ingormation to workby determining the heritable characteristics of organisms C: third,genes had to easily copied,because all of a cells genetic information is replicated every time a cell divides
What do all the organisms of the same species living in an area at the same time make up?
a population
How do genes play a role in evolution?
Evolution is, the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms. Genes are the hard heritability material that carry successful variation unto the next generation of organisms. They are also the ultimate target of natural selection in individual organisms. An organism with a gang of successful genes is reproductively successful and passes those traits on to future generations; into the populations gene pool.
Does natural selection cause a change in the gene frequencies of the population over time?
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
What is the rule of genes in evolution?
The " rule " of genes? An allele is a different molecular form of the same gene. So, the evolutionary definition. Evolution is the change in allele frequency over time in a population of organisms. That is their " role " if that is what you mean. They are the molecules that are inherited, thus causing changes over time in populations, which is evolution.
What organisms live in the southwest of china?
the answer to this is thAT WHEN other animals have sex they reproduce and have other baby animals that inherit the same genes. but this animal can also change its genes over time when mating with another animal that isnt its species
What does the evolution theory say in the present time?
The same thing it says has happened for millions of years, and the same thing that will happen in millions of years to come. Organisms which can survive better will pass on their genes more often, until the species is suited to the environment.
What is the deffanition of population?
it is how many organisms live in the same place at the same time. - ORGANISMS= any living thing
A group of the same kind of organisms that live in the same are at the same time?
Population

population
What is A group of the same kind of organisms that live at the same area at the same time?
Its the Population
What happens to Genes located in different regions of the body during embryonic development may?
the options are a. turned on and off b. never turned on c. turned on and left on d. activated for only a short time in one cell and a long time in another cell e. all of these
How is gene theory related to theory of evolution?
Genes are the hereditary molecules that natural selection actually selects, So, the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms is the definition of evolution.
