Quick answer
Genotype: definition
A genotype is the specific combination of gene variants (alleles) you carry at a given location in your DNA — one inherited from each parent.
Genotype, explained
For example, at MTHFR C677T your genotype may be CC, CT or TT. Your phenotype is the observable trait, which results from genotype plus environment.
