Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
What cause variation on an expected number on monohybrid cross?
The cause of variation are firstly genetic itself, 2nd) crossing over, 3rdly) indipendent assortment
What are the Technologies that affect biological diversity?
Technologies that affect biological diversity include genetic modification. This will cause a loss in biodiversity.
What terms defines chance in allele frequency that have a big effect in small populations?
Genetic driftChanges in the frequency of alleles within a population is called genetic drift. Over time, this can cause a significant phenotypic shift from other populations of the same species that have not had the same genetic drift. Given enough time, genetic drift can be significant enough to cause the affected population to be reproductively isolated from the rest of its species and eventually will develop into a new species.
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
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.
Relate genetic variation and mutations to each other?
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.
How is genetic variation related to a species chance of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the benefits of genetic variation and what are the potential problem that it can cause?

What factors cause variation in the atmosheric elements?
genetic factors
What can a genetic mutation cause?
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
