Genotype

Definition - What does Genotype mean?

A genotype refers to an organism’s complete set of unique characteristics at the genetic level. This is as opposed to its phenotype, which is the outward expression, or physical appearance coupled with its traits, based on its genotype.

More specifically, the genotype is the result of the combination of a gene’s alleles, which are the various forms of genes, either standard or mutated, and dominant or recessive.

Hydrolife explains Genotype

Organisms with identical alleles are known as homozygous, whereas those with different alleles are known as heterozygous.

All new species of living things are the result of new genotypes or the result of how a genotype interacts with its environment. This can explain why a plant grown from seed may display different characteristics than another plant grown from seed from the same flower.

Their genotypes may be almost identical, but any slight change or interaction can result in different appearances or growth patterns (phenotypes).

Conversely, two or more plants may express similar or near-identical characteristics in height, flower type, and length, etc. but have different genotypes.
