What is a difference within a population?
A variation within the population. Height in humans is an example of this.
What is decontinuous variation?
Variation within a population in which few or no intermediate phenotypes fall between the extremes.
What term is used by biologists to describe the differences within a population with respect to features such as height?
The term used by biologists to describe the differences within a population with respect to features such as height is "variation". Variation refers to the range of different traits or characteristics that individuals within a population exhibit, including height.
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
What kind of variation must exist in a population that has a wide range of phenotypes?
Genetic variation must exist within the population, meaning individuals have different alleles. This genetic diversity results in a wide range of phenotypes that can be observed. Environmental factors can also contribute to phenotypic variation within the population.
Is mango leaf a parallel variation?
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
Which is an activity that increases the genetic variation within a population of earthworms?
sexual reproduction
What movements of individuals into or out of a population provides a source of?
Migration of individuals into or out of a population provides a source of genetic variation. This movement introduces new genes into the gene pool, increasing diversity within the population.
How do alleles of genes contribute to genetic variations within a population?
Alleles are different versions of a gene that can result in different traits. When individuals in a population have different alleles for a gene, it leads to genetic variation. This variation can result in differences in physical characteristics, behaviors, and other traits within the population.
A bell shaped curve of phenotypic variation is a representation of?
A bell shaped curve of phenotypic variation is a graphical representation of the distribution of a trait within a population. It shows that most individuals in the population have an average value for the trait, with fewer individuals on the extreme ends of the spectrum.
How is an allele described in terms of its specific genetic variation within a population?
An allele is a specific form of a gene that can vary within a population, leading to different traits or characteristics.
