| Front | genetic causes of variation 4.2.2(f) |
|---|---|
| Back | genetic causes include - alleles (genes have diff alleles with diff effect depending on parental combination of alleles) - mutation (change in DNA sequence so diff proteins, affecting physical/metabolic characteristics, occurs in body cells (individual affected) or gametes (can pass to offspring) both causing variation - meiosis (independent assortment and recombitant DNA) - Sexual repro (offspring inheits alleles of both parents, so differs from parents, more variation than asexual which produces clones genetically identical to parents) |
