If a certain species has little genetic variation what could lead to its rapid extinction?
Genetic bottleneck causes very little genetic variation and can cause genetic drift.
How might using mass selection and inbreeding hurt a species' chances for survival?
Because it will decrease the genetic diversity of the population.
What does neutral variation mean?
Genetic diversity that confers no apparent selective advantage.
What make small populations vulnerable to extinction?
there are several factors that make small populations vulnerable. First off there are demographic factors. If a small population faces a forest fire, they are more susceptible to extinction opposed to a large, wide-spread population. you also have the lack of genetic availability. without genetic variation, a species can become prone to disease. there are many more, and I could go on.
What part of a nucleotide accounts for the genetic variation between individuals?
A) sugar B) phosphate C) base ) polymerase
What would decrease genetic variation in a population?
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
What would most likely decrease the genetic variations in the human population?
Which would most likely decrease the genetic variation in the human population?
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
Which environmental factor would likely lead to an increase in genetic variation in population of squirrels?

Do you no two examples of Inherited variation?
genetic and environmental variation
Which would likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
Why is low genetic variation a problem?
Low Genetic variationis the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction.
What can the variation become?
The variation can either increase or decrease depending with the genetic factors.
What is heritability coefficient?
total variation in the phenotye (IQ, introvert) that can attribute to genetic rather thatn environmental variation in the population, it is ALWAYS about groups NEVER about specific individual like Me or YOU :-)
Write an original definition for genetic variation?
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
