Dna: genetic material that makes up chromosomes; resembles twisted ladder, strands of sugar and phosphates connected by rungs made from nucleotide molecules of adenine, thymine, guanine, cytosine. Chromosomes: threadlike structures in the nuclei of living cells; contain genes. Genes: small units of dna that guide the creation of proteins which make up our physical structures and regulate development and physiological processes. Alleles: alternative forms of the same gene, pair of genes at a given locus. Homozygous: each parent contributes the same allele for a particular gene. Heterozygous: each parent contributes different alleles for a particular gene. Dominant: trait that is exhibited when an individual possesses heterozygous alleles at that locus, eg. Recessive: trait that occurs only when it is expressed by homozygous alleles, eg. Genotype: an organism"s genetic makeup; genetic makeup of a trait, represents what was inherited. Phenotype: represents physical and behavioural manifestation of an organism"s genotype through interactions with the environment.
