What else can I help you with?
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
Discribe what biodiversity means?
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
Why does sexual production result in more genetic variation in a species?
It mixes the chromosomes of the two parents
How does genetic variation prevent extinction of a species?
Genetic variation allows individuals within a species to have different traits that might be advantageous in changing environmental conditions. This diversity increases the chances that some individuals will survive and reproduce when faced with new threats or challenges, helping to prevent extinction. High genetic variation also provides a larger pool of traits for natural selection to act upon, promoting the species' ability to adapt over time.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
How genetic variation is measured?
Gentic variation is mearsured by the number of species in the given area not.
Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
How does variation in a species help the species survive?
As each new generation is produced, genetic variation may be introduced into a population. The more genetic variation in a population, the more likely it is that some individuals might have traits that will be advantageous if the environment changes.
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
What does meiosis do for species?
Meosis creates gametes (reproductive cells) and allows genetic variation of the species
What is variation among members of the same species called?
Variation among members of the same species is called genetic diversity. This diversity arises from differences in genetic makeup, leading to variations in traits such as physical appearance, behavior, and susceptibility to diseases. Genetic diversity is important for a species' ability to adapt to changing environments and to evolve over time.
Discribe what biodiversity means?
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
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
What is a result of the limited genetic variation in the current cheetah population compared to earlier cheetah populations with more variation?
d. current populations of cheetahs are able to interbreed with other species, increasing genetic variation.
