    What genotype versus environment means in Biology A-Level, as defined for AQA.

    Definition of genotype versus environment

    Check what you remember

    Read the wording for your board, then hide it and explain genotype versus environment in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: AQA

    Monozygotic twins share their alleles, so phenotypic differences between them are largely attributed to environmental factors, though somatic mutations and epigenetic effects also contribute.
