What characteristic within populations causes natural to occur?
genetic variation
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.
Why is it important that variation exists within populations of a species?
Without variation there is nothing to select for against the background of an immediate environment and thus no evolution as alleles, not selected for, would not change over time in this population of organisms. Without variation the environment can change quickly and send your population to extinction if there were no variants that could meet this challenge.
What characteristic within populations causes natural selectio?
Variation in traits within populations is the characteristic that causes natural selection. This variation could be due to genetic differences or environmental factors, and individuals with traits that are better adapted to their environment are more likely to survive and pass on their genes to the next generation. Over time, this process leads to the evolution of populations as adaptations become more common.
What is a result of the limited genetic variation in the current cheetah populations compared to earlier cheetah populations with more variation?
d. current populations of cheetahs are able to interbreed with other species, increasing genetic variation.
What evolutionary force is most likely to decrease variation between two populations?
evolutionary forces is most likely to decrease variation between populations
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.
Is the variation in weight in human populations an example of discrete or continuous variation?
It is an example of continuous variations.
Why are there so much variation with a species?
Variation within a species is due to genetic diversity, which arises from random mutations, recombination during reproduction, and gene flow from other populations. This variation provides the raw material for natural selection and enables species to adapt to changing environments.
How does standing genetic variation contribute to the overall genetic diversity within a population?
Standing genetic variation refers to the existing genetic differences within a population. This variation contributes to genetic diversity by providing a pool of different genetic traits that can be passed on to future generations. This diversity helps populations adapt to changing environments and increases their chances of survival.
Why are studies important?
Biological studies are important for monitoring environments and changes within them. They are important for monitoring populations for the purpose of preservation and conservation.
What kind of science deals with heredity and variation of organisms?
Genetics is the kind of science that deals with genes, heredity and variation.
