Chromosomes and genes | Inheritance and variation | Middle school biology | Khan Academy

[@BioAnswersStudent]

I wanted to ask a question to clarify some simple concepts. We always hear that we have two copies of every gene (one from father and another from mother). When we say that, do we mean the 5-3 strand and 3-5 strand double stranded DNA? Or do we mean that there are actually two copies of the gene, each having its own 5-3 strand and 3-5 strand?
