Biological determinism, also known as genetic determinism, [1] is the belief that human behaviour is directly controlled by an individual's genes or some component of their physiology, generally at the expense of the role of the environment, whether in embryonic development or in learning. [2]
The determination of a cell to a particular fate can be broken down into two states where the cell can be specified (committed) or determined. In the state of being committed or specified, the cell type is not yet determined and any bias the cell has toward a certain fate can be reversed or transformed to another fate.
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.

Population genetics is the branch of evolutionary biology responsible for investigating processes that cause changes in allele and genotype frequencies in populations based upon Mendelian inheritance. [3] Four different forces can influence the frequencies: natural selection, mutation, gene flow (migration), and genetic drift. A population can ...
In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.
A sex-determination system in which the sex of an individual organism is determined by the number of sets of chromosomes it possesses: offspring which develop from fertilized eggs are diploid and female, while offspring which develop from unfertilized eggs are haploid and male, with half as many chromosomes as the females.
Determined: A Science of Life Without Free Will is a 2023 nonfiction book by American neuroendocrinology researcher Robert Sapolsky concerning the neurological evidence for or against free will. Sapolsky generally concludes that our choices are determined by our genetics , experience, and environment, [ 1 ] and that the common use of the term ...
