__Homozygous__ - 2 of the same Allele relating to the same feature

__Heterozygous__ - 2 Different Allele's relating to the same feature

-A form of gene, 2 types in each person, one from mum, one from dad (e.g B b Brown hair (B) blond hair (b)
 * __Allele__**

__Dominate__ -A gene that over rides another e.g B,b person displays Brow hair

__Recessive__ -A gene that is only shown if the person has 2 recessive genes (e.g b,b for blond, can be carried in people and not shown e.g B,b has brown hair but still carries blond gene)

__Genotypes__ -B,B is a genotype of a person, what genes a person has

__Phenotype__ -What the genotype actually looks like e.g BB is Brown hair.
