| Anaerobic respiration | Fermentation |
| The fusion of 2 (haploid) gametes to for a (diploid) zygote | Fertilisation |
| A haploid sex cell which is capable of fusion | Gamete |
| A unit of DNA which codes for the production of a specific protein | Gene |
| Has different alleles (for a trait) | Heterozygous |
| has identical alleles for a trait | Homozygous |
| A biological catalyst which is fixed to an inert material by chemical or physical means | Immobilised Enzyme |
| The genetic make-up of an individual | Genotype |
| The passing on of traits from parent to offspring by means of genes | Heredity |
| Genes located on the same chromosome ( are said to be linked) | Linkage |
| Manipulation or alteration of genes | Genetic Engineering |
| Having one set of chromosomes | Haploid number |
| During gamete formation each member of a pair of alleles may combine randomly with either of another pair | Mendel's 2nd Law the law of independent assortment |
| All the chemical reactions that occurs in organisms | Metabolism |
| Neither allele masks the expression of the other | Incomplete Dominance |
| A form of nuclear division in which one(diploid)nucleus divides to form four different(haploid) (daughter) nuclei | Meiosis |
| A form of nuclear division in which one nucleus divides to form 2 identical (daughter) nuclei | Mitosis |
| Traits are controlled by pairs of alleles which separate at gamete formation. each gamete carries only one allele for each trait. | Mendel's first law the law of segregation |
