What are the different forms of a gene that decide a characteristic known as?
Each allele has two forms which are known as alleles. Alleles play an important role as to which characteristics either from mother or father will be passed along to the next generation. The way in which alleles are expressed is the study of genetics.
What role does competition play in the theory of natural selection?
Natural selection needs competition in order to occur
What type of selection that humans control?
Artificial selection.Artificial selection is the selection, by humans, of which individual plants or animals to breed from. In this way desirable characteristics, such as increased yield or disease resistance, can be preserved or improved.Charles Darwin used artificial seletion as a model for how evolution could take place in nature, where competiton between individuals replaced the selective action of humans. He called the natural process 'natural selection'.See http://evolution.berkeley.edu/evosite/evo101/IIIE4Evochange.shtmlfor an excellent account.
What best describes diversity in terms of natural selection?
Diversity is the number of different role players (species) in an area. I like to think of diversity in the form of niches. The number of niches being filled in an ecosystem is directly related to the diversity.
What is the role of x-gal iptg in selection of recombinants?
to differenciate recombinant dna from non recombinant
What role do meiosis play in process of natural selection?
Meiosis plays an important role in the process of natural selection, as it allows DNA to replicate.
Which form of natural selection is most likely to play a role in speciation?
Disruptive Selection
What is the role of the natural selection in evolution and what role does it play in environmental science?
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
What role does the environment play in Darins theory of evolution by natural selection?
The environment is the '' natural selector. ''
What role does the environment play on natural selection?
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
What is the the role of natural selection in evolution and what roles does it play in environmental science?
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
What role does the environment play natural selection?
toilet paper...... just kidding it helps the plants grow and people live
How do humans affect artificial selection?
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
How do chromosome segregation and independent assortment play a role in natural selection?
They both fuel the engine of genetic diversification by creating changes to the linear structure of Dna.
How do humans affect selection What role does nature play?
