What is the difference of phenotype and genotype?

The genotype is the set of genes in our DNA which is responsible for a particular trait. The phenotype is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different genotypes.

I hope this is useful, JunhoaZ!^_~!

A genotype is your genes themselves, the phenotype is the appearance of those genes The phenotype is what you see and the genotype is just all of your genes
