Ingenetics, variation refers to an individual that possesses characteristics different from the others of the same kind. Genetic variation usually arises as a mutation in a gene that encodes a protein or an RNA. Variations may be reflected in the phenotype of the individual, e.g. a difference ...

Moreover, a few morphological characteristics show comparable examples of variety in various varieties, making it conceivable to test whether the equivalent or various qualities underlie comparable phenotypes. In spite of these favorable circumstances, the pigeon is underused as a model for the sub-...
1. the causes of genetic variation are the focus of this lesson. In the section of biological heredity, the teaching materials have spent a considerable amount of time helping students understand why the biology is inherited and what the genetically determined material is. Therefore, students ...
Aspects of the reproductive and maturation biology of the brown shrimp Crangon crangon (L.) were studied in various subareas of the German Bight (North Sea). The size-specific sex ratio of C. crangon was examined based on length frequency distribution data. The sex ratio for the smallest siz...
Background: Stable isotope analysis is increasingly being utilised across broad areas of ecology and biology. Key to much of this work is the use of mixing models to estimate the proportion of sources contributing to a mixture such as in... AC Parnell,R Inger,S Bearhop,... 被引量: 2156...
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potenti
The extent of interspecific gene flow and its consequences for the initiation, maintenance, and breakdown of species barriers in natural systems remain poo
What does allelic mean in biology? Allelic refers to alleles, which are usually the same gene locus. This is usually used when there is the presence of different variations of an allele that cause the expression of a disease or condition. ...
As numerous examples highlight, an understanding of normal range variation is not arcane knowledge; it is essential to clinical practice. Clinicians encounter variations on a daily to weekly basis, and advances in imaging have made it easier to detect variations in living patients. Ignorance of ...
