What is discontinuous variation?
A characteristic of any species with only a limited number of possible values shows discontinuous variation . Human blood group is an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible (A, B, AB or O).
What is environmental variation?
the ability of an organism to alter greatly its PHENOTYPE depending upon environmental conditions. The phenomenon is seen most clearly in plants, perhaps because they are fixed in the ground.
What is phenotypic variance?
VP, or phenotypic variance, is simply the observed, measured variance in the trait of interest. For instance, if you are studying milk yield, then the observed variation in milk yield among the cows is your VP.
What is nucleotide variability?
Nucleotide variability is genetic variation at the level of nucleotide sequence of DNA (deoxyribonucleic acid) and the genetic variability is a variation on whole gene level. A little change in any one of nucleotide is enough to make a change in gene.
What is discontinuous variation caused by?
Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The environment has little effect on this type of variation. In continuous variation there is a complete range of measurements from one extreme to the other.
What does discontinuous mean in biology?
biology. : abrupt variation in which there are few or no intermediate forms.
What is genetic variation and environmental variation?
The main difference between genetic variation and environmental variation is that genetic variation is the variation of the genotype between two individuals within the same species whereas environmental variation is the dependence of the phenotype upon the environmental factors.
What is environmental variation and examples?
Environmental Variation Many features we see in organisms are caused by the environment in which they live. For example, environmental variations in humans could be: Hair length – what length you choose to have your hair. Scars – caused by accidents personal to you.
What is the difference between phenotypic variation and genetic variation?
Phenotypic variation was positively linked to precipitation variability, whereas genetic diversity was correlated with the position of populations, suggesting that both types of variation are shaped by different processes.
What is nucleotide diversity and why is it important?
Nucleotide diversity refers to the relative proportion of nucleotides A, C, G and T present in every cycle of the run. Well-balanced or high diversity libraries have roughly equal proportions of all four nucleotides in each cycle throughout the sequencing run.
