What does the term strain mean as it is used in genetic crosses
LUCKY_DIMON [66]

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).

What kind of organism is a heterotroph?
Harman [31]
<span>These organisms are called autotrophs. Autotrophs are also called 'self-feeders,' and they are able to produce energy from sunlight and carbon dioxide and are therefore known as 'producers.' The only autotrophs that we know of are plants and some types of algae. This makes all other organisms heterotrophs</span>
