Genotype is all the information / genetic material of an individual.
the genotype is constituted by the set of hereditary characteristics specific to an individual and the phenotype corresponds to the expression of this genetic inheritance in a given environment. It reports on the anatomical and physiological characteristics of an individual. The existence of dominant and recessive genes explains that the same phenotype corresponds to different genotypes.
Phenotype is your physical characteristic as Brown for the color of your eyes or blond for the color of your hair
While Genotype is the combination of genes that you have (basically your two parents give you a genes for a characteristic and that's the scientific expression) so B = a hairy brown and b = a blond so you can have BB = you're brown Bb = you're brown or bb = you're blond
So for example your phenotype is to be brown and your genotype is either Bb or BB
