In biology, the strain is a low-level taxonomic rank used in different contexts:
In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.
In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.
A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).
Answer: The group of participants who are exposed to the independent variable. These participants receive or are exposed to the treatment variable.
Explanation:
Environmental factors often influence traits independently of genes. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.
How do environment and gene determine our personality?
Some genes increase the characteristic and others work to decrease the same characteristic-complex relationship among the various genes, as well as a variety of random factors, produce the final outcome.
Because of their genetic makeup, individuals differ in their responsiveness to the qualities of the environment. There are unique, genetically influenced reactions to particular experiences to which we are exposed.
The presence of drugs and chemicals in an organism's environment can also influence gene expression in the organism. The environment can affect morphological and physiological development whereas genes influence morphology and physiology, creating a framework within which the environment acts to shape the behavior of an individual.
Hence in this way, genes and environmental influences work together to determine our characteristics.
