The genotype is the set of genes in our DNA which is responsible for a particular trait. The phenotype is the physical expression, or characteristics, of that trait.
GENOTYPEPHENOTYPEDefinitionThe genetic makeup of an individual. Refers to the information contained on two alleles in the cell.Detectable expression of the genotype. An expressed and observable trait. e.g. hair color.ExamplesDNA,susceptibility to diseasesHair color,eye color,weight,theabilitytorollone′stongueDepends uponThe hereditary information that was given to an individual by their parents.Genotype and the influence of the environment.InheritancePartly inherited by offspring,as one of the two alleles is passed on during reproduction.Cannot be inherited.ContainsAll the hereditary information of an individual,even if those genes are not expressed.Expressed genes only.Can be determined byGenotyping–using a biological assay,such as PCR,to find out what genes are on an allele.(Inside the body)Observation of the individual.(Outside the body)
