What else can I help you with?
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
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 are the possible causes of genetic variation?
Anaphase 1 - the crossing over of chromosomes, they swap genetic material determining what you genetically inherit
A change in the genetic material that produces variation in a species may be the result of?
immigration, mutation and sexual reproduction.
Which would most 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.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the 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.
If a certain species has little genetic variation what could lead to its rapid extinction?
A lack of genetic variation can make a species less able to adapt to changing environmental conditions or new threats like diseases or predators. This reduced ability to adapt increases the species' vulnerability to extinction if they cannot effectively respond to these challenges.
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 the major cause of variation within species?
Genetic mutations are the major cause of variation within species. Mutations can introduce new genetic traits that can be passed on to offspring, leading to diversity within a population. Other factors like genetic recombination, migration, and environmental influences can also contribute to variation within species.
How is genetic diversity to beneficial to a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity beneficial to species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
