Genotype vs. PhenotypeContinue filling in your Vocabulary Chart using the definitions and examples provided here.Learning targetI recognize that genes carry information which determines traits.GENE & traitGene: One section of DNA with instructions for a trait

Trait: A characteristic or feature determined by genes.

You have genes for each of the following traits:Hair colorEye colorHitchhikers thumbTongue rollingHeight

alleleThe different forms of a gene.

Examples:Hitchhikers thumb OR Straight thumbCan roll tongue OR Cant roll tongueBlonde hair OR Black hair OR Brown hair OR Red hair

(Note: One allele comes from each parent.)

DominantAlleles that cover up all other alleles.Hides, covers, masks, or over-powersAlways shows up when present (it dominates!) Shown with UPPERCASE letters.

Examples:HBARecessiveAlleles that get covered up by dominant alleles.

Shown with lowercase letters.

Examples:hba

HomozygousWhen both alleles are the SAMEHomo = same

Examples:HH = homozygous DOMINANT hh = homozygous RECESSIVE

heterozygousWhen both alleles are DIFFERENTHetero = different

Examples:HhQqRr

GenotypeThe genes that an organism has(Genotype = Genes) Represented by letters

Examples:HhBBttQqPhenotypeThe traits or characteristics of an organismWhat it looks like(Phenotype = Features)
