When is genetic drift a major factor to evolution?
When there is low gene flow (apex 10.1.2)
How might genetic drift alter the diversity of a population?
Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
Does the influenza virus readily change the expressions of its genetic material?
RNA genome of influenza virus is segmented in to 7 pieces. It has the unique property of undergoing two types of genetic variation ie antigenic drift and antigenic shift. In antigenic drift the antigenic variations are minor where genetic recombination take place between strains of two similar species whereas in antigenic shift the recombination take place between strains of dissimilar species leading to major antigenic variations and hence seasonal epidemics.
What is the major source of energy for continental drift?
convection currents
Genetic recombination generates diversity in what part of the immune system?
Genetic recombination is a major factor contributing to cell-mediated immunity. Different B cells and T cells are able to recognize a wide variety of targets because of the genetic recombination they undergo in developmental stages.
When is genetic drift major factor of evolution?
When there is low gene flow
When genetic drift a major factor of evolution?

When is genetic a major factor of evolution?
When there is low gene flow
Does genetic drift lead to evolution?
Yes. Genetic drift-- the change in allelic frequencies of a population due to chance-- can play a major role in evolution. The effects of drift are most pronounced in small, isolated populations. Drift can bring alleles to fixation very quickly in such populations, and can lead to genetic differentiation between them, possibly contributing to speciation.
When is genetic drift a major factor in evolution?
When there is low gene flow When there is no selective pressure When there is a bottleneck

Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
What has the author Brett Calcott written?
Brett Calcott has written: 'The major transitions in evolution revisited' -- subject(s): Evolution (Biology), Biodiversity, Population genetics, Genetic transformation
Which of the following is a major factor leading to extinction?
Which of what? I can't answer your question if it's vague like this.
When was The Major Transitions in Evolution created?
The Major Transitions in Evolution was created in 1995.
What are the basic driving forces behind evolution?
the driving forces behind evolution are Mutation, Natural Selection, Gene flow, and Genetic drift So lets start with Natural selection, all this means is that that individuals best suited for their environment are more likely to survive and reproduce. That's all it is, Individuals with certain inherited traits leave more off spring than others. an example of natural selection would be anti-biotic resistance in bacteria. Now mutations, Mutations are random and can be beneficial, neutral, or harmful to an organism, however not all mutations matter in evolution. only those that can be passed on to the next generation matter. Those that occur in somatic cells do not matter to evolution. Genetic drift - change in the gene pool of a small population due to chance. an example. Disasters such as the BP oil spill occur which kills off a large number of individuals, this results in a drastic reduction of the population size which in turn affects the genetic variation. and finally Gene flow which is when individuals migrate between populations, this brings in more genetic variation.
