When the population is small
or
When there is no gene flow
Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.

∙ 11y agoWhen it is a beneficial mutation and allows the organism receiving it, or the organisms receiving the mutation through the mutated organisms sex cells, to survive and be more reproductively successful and leave many progeny.
Then evolution, the change in allele frequency over time in a population of organisms, has taken place.

When the population is small
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
What type of genetic change is most important for evolution?
Evolution is the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms.
Which sex is most likely to be affected by a negative Y linked recessive trait?
Men have 1 X chromosomes and Women have 2. This means, that men are more affected by the x linked recessive disorder as they only have one chance to get a non mutant allele. See the wikipedia extert below for more info."In humans, generally "men are affected and women are carriers" for two reasons. The first is the simple statistical fact that if the X-chromosomes is a population that carry a particular X-linked mutation at a frequency of 'f' (for example, 1%) then that will be the frequency that men are likely to express the mutation (since they have only one X), while women will express it at a frequency of f2 (for example 1% * 1% = 0.01%) since they have two X's and hence two chances to get the normal allele. Thus, X-linked mutations tend to be rare in women."
Which is most inclusive A. Allele B. Genotype?
single genes wiht multiple alleles
Which kind of mutation is most likely to produce a protein with one extra amino acid?
A frameshift mutation
Under is condition would a mutation have most impact on allele frequency?
There is no gene flow.
When does mutation have a most impact on Allele frequency?
When the population is small or When there is no gene flow Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.

Which of the following situations is most usual for a dominant allele that results in severe effects in the offspring?
The trait occurs by mutation.
What is potential impact mutation?
No one knows what effect a mutation may have. Most are not viable.
What do mutations do to alleles?
Generally, gene frequency will not change significantly unless the mutation is successful and advantageous enough that it is heavily selected in the population. Since most mutations result in failure of the organism to thrive (death, reproductive failure, etc.) they have little or no effect on a population's gene frequencies. Even if the mutation has no apparent detrimental effects it will, itself remain in the population at a low frequency unless it enhances the organism's ability to reproduce within the population.
What will most likely happen if the exposure to insectisides causes mutations to a certain species over generations?
Evolution. Certain ones of the insect species will have resistance to the insecticide due to mutation and these organisms will survive and reproduce, thus conferring this resistance on to their offspring. The change in allele frequency, the definition of evolution.
What is the probability that a new allele will be lost in the next generation?
New alleles are the result of mutation. When that allele appears in the population, it is at a very low frequency, and can be lost very easily. For example, consider an allele arising in an individual. Half of his gametes will contain the allele. Therefore, his offspring (assuming, of course, he finds a mate and has any offspring at all) only have a 50% chance of carrying the allele. If he from a species with low fecundity, there is a very good possibility that none of his offspring will have the allele and it will be lost from the population. It is estimated that only 1/3 of new mutations make it into the next generation because most are lost due to chance factors.
How is mutations a basis for evolution?
Mutation serves up the variation in morphology and behavior that natural selection promotes, against the immediate environment, to better survival and, most especially, reproductive success. The organism that is selected thus has more progeny than it's conspecifics and changes the allele frequency in it's population of organisms, and this is evolution,
Does mutation depend on evolution?
The mutation theory is basically stating that mutation is one of the major factors that cause evolution. The mutation has to be a beneficial mutation, meaning that it has to help the survival of the organism that got the mutation. The mutation causes knew genes and diversity which can spread quickly throughout a population and eventually change the frequency of alleles (causes mutation) Remember the mutation has to be beneficial to the survival of the organism.
What type of genetic change is most important for evolution?
Evolution is the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
