Does gene flow spread advantageous mutations?
Yes but it could also spread deleterious mutations. It depends on the size of the gene pool.
Are mutations the only way to add new genes to a gene pool?
yes. independent assortment and crossing over in mitosis will add new combinations of alleles to the DNA but only mutations will create new genes.
If a trait has no effect on an organisms fitness what would likely happen to the allele for that trait?
Perhaps nothing. Any trait that natural selection is blind to could pass, but many would pick-up deleterious mutations as the organisms possessing such traits would not be eliminated from the gene pool. Great ape vitamin C synthesizing pathways are one example of this. One gene coding for a part of this pathway has been ' knocked out ' by mutations and great apes ( including us ) can not synthesize vitamin C.
What are the two types of gene shuffling?
Gene shuffling means the genetic recombination and mutations of a gene pool of a species where genetic recombination is the mixture of parent alleles that are passed on and the mutations are the random changes in an organisms DNA that are passed on.
What type of heat transfer will occur between the heated water in a heated pool and yourself?
conduction
How can new mutations be added to a gene pool?
Mutations are added to a gene pool when a mutation (completely random) occurs in a person. They will pass this gene on to their offspring (and so on, and so forth).
Does gene flow spread advantageous mutations?
Yes but it could also spread deleterious mutations. It depends on the size of the gene pool.
What can lead to the development of new mutations in the gene pool?
do it own your own ;p
What are the main principles of animal evolution?
Animal evolution is not a linear set of rules or stages, but rather a branching process. Main principles include that mutations occur in a species and are tested by the environment, and the successful mutations live long enough to be passed down to offspring and continue through the gene pool. This is Darwin's theory of natural selection.
How molecular mechanisms can introduce variatian into the gene pool of plant or animal population?
Mutations in the DNA code can introduce variation into the gene pool of a population.
Does a thermocline occur in a swimming pool?
no

How many events in the Olympics occur in the pool?

How do new traits arise to create genetic variability?
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
