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.

∙ 10y agoWhen an allele has no effect it becomes subject to "genetic drift"; random mutations will occur and accumulate over time. When these mutations occur at a known rate, their number can be used to estimate when the last common ancestor of two current organisms lived.

What happen when a population is is Hardy-Weinberg equilibrium?
Allele frequency is stable
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.

Explain how the founder effect can cause a change in the frequency of alleles in a population?
Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the "raw material" for natural selection.
How can micro evolution happen?
By simple genetic recombination for one. microevolution is just evolution and evolution is the change in allele frequency over time in a population of organisms. Just change over time short of speciation and especially valid for sexually reproducing organisms who always change allele frequencies through coitus and reproduction.

What is the term for changes in allele frequency that happen randomly one generation to the next?
Genetic drift
If a trait made an organism less likely to survive and reproduce what would happen to the allele for the trait?
The allele would not be passed on to further generations, as the organism cannot reproduce. There would be a smaller population of that organism who's genetic code does not contain the allele for that particular trait.

What will happen to the other organisms if the koala endangered species continues to decline?
Koalas are not endangered.Other organisms are unlikely to be affected in a major way if the koala does die out. This marsupial has all but disappeared from some parts of eastern and southern Australia, with no noticeable effect on the environment.
