allels different forms of genes
phenotype geneticists call how a trait appears or is expressed
genotype 2 allels that control the phentontype of a trait
homozygous 2 allels of a gene are the same its genotype
heterozygous if the 2 allels of a gene ore different
punnet square is a model used to predict possible genotyps and phenotyps of offspring
codominance allels can be observed in a phenotype t
polygenic inheritance occurs when multiple genes determine the phenotype of a trait
DNA an organisms genetic material
nucleotide is a molecule made of a nitrogen base a sugar and a phosphate group
RNA a type of nuceic acid that carries the code for making protiens from the nuceus to the cytoplasm
