The importance of genetic factors has recently been at least halved by the discovery of Epigenetics.

Which is a characteristic of an ecosystem in approximate equilibrium A. The kinds of organisms do not change. B. Biotic factors do not change. C. Abiotic factors do not change. D. The total number of?
The total number of organisms don't change. which would be D :)
The change in the inherited traits of populations of organisms over time is known as?
It is called genetic drift.
What is evolution in genetic terms?
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
Two factors that are responsible for a phase change?
Change in pressure and change in temperature.
Would evolution stop if there were no natural selection?
No, but adaptive change would be difficult. Remember, evolution is the change in allele frequency over time in a population of organisms. Mutation, genetic drift, genetic flow and other processes would continue without natural selection.

What are the Factors that are responsible for a change in demand?
nothig really
What is the genetic definition of evolution?
Evolution is the change in allele frequency over time in a population of organisms.
What does genetic varation really mean?
since GENETIC is the compilation of DNA strands to form a gene that acts as a determinant to the growth pattern of an organism, that is the type of hereditary information the organism posses. and VARIATION is a change that exist between organisms..... thus; the word genetic variation is a change that exist between organisms of a particular specie as a result of change(s) that has occurred in their gene....
What does evolution mean in sicence trem?
To be strictly genetic; evolution is the change in allele frequency over time in a population of organisms. Loosely; evolution is change over time in living organisms.
The change in the inherited traits of populations of organisms over time is known as?
It is called genetic drift.
Random change in the frequency of a gene is called?
A random chamnge in the frequency of a gene is called genetic drift.There is disagreement about how much genetic drift occurs in nature, but it cannot be responsible for producing adaptations. Natural selection is the only known scientific mechanism for producing the adaptations which we see in all organisms.
What are the factors that are responsible for change of state of substance?
temperature nature of surroundings
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
What is evolution in genetic terms?
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
What effect does genetic drift have on organisms?
Genetic Drift (or allelic drift) is the pseudo-random chance that a minor genetic change will eventually become a fixed genetic inheritance in a specific organism. IT is the underlying principal in the theory of evolution. There are many equations and probabilities involved, but the basic explanation is that as the number of generations with the genetic change increases, so does the chance that the change will become the norm, rather than the aberration.
What ideas Darwin's based on fossils and the modern organisms he found basically says that genetic change are inherited by later generations?
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
