Biology definition of variation
WebVideo transcript. - [Instructor] We are now going to discuss molecular variation in cells. You are probably familiar with the idea that you have a variation of genetic makeups in a population. But even within an organism you have variation in the types of molecules that an organism can produce and when they produce them. Webbiological variability: The natural variability in a lab parameter due to physiologic differences among subjects and within the same subject over time. Types of Biological Variability • Interindividual—Differences between subjects due to differences in diet, genetics or immune status. • Intra-individual—Differences in the same subject over ...

Webgene flow, also called gene migration, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population. The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits. …
