Genetics involves the expression, transmission, and variation of inherited characteristics.

Theory of genetics[edit]

Def. a "branch of biology that deals with the transmission and variation of inherited characteristics, in particular chromosomes and DNA"[1] is called genetics.

Evolutionary genetics[edit]

Molecular genetics[edit]

Def. a "field of biology which studies the structure and function of genes at a molecular level"[2] is called molecular genetics.


Def. a "science that combines optics and genetics to probe neural circuits"[3] is called optogenetics.

Population genetics[edit]

Def. the "study of the allele frequency distribution and change under the influence of the four evolutionary processes: natural selection, genetic drift, mutation and gene flow"[4] is called population genetics.

Quantitative genetics[edit]



  1. Individual breeding preferences coupled with geographical isolation may produce new species.

Control groups[edit]

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[5] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[6]"[7]

Cavia porcellus may be derived from Cavia tschudii.

Proof of concept[edit]

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[8] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[9]
