The actual alleles inherited.

• Genotype

• Phenotype

• Alleles

• Genes

The physical characteristics or traits of an organism

• Genotype

• Phenotype

• Allele

• Gene

Different versions of the same gene.

• Genotype

• Phenotype

• Allele

• Gene

Sections of DNA that provide instructions for making proteins.

• Dominant

• Recessive

• Alleles

• Genes

2 different alleles. Example: Aa

• Heterozygous

• Homozygous

• Recessive

• Dominant

2 of the same alleles. Example: AA or aa

• Heterozygous

• Homozygous

• Recessive

• Dominant

Allele will always have that trait expressed (seen).

• Dominant

• Recessive

• Heterozygous

• Homozygous

Allele will only have that trait expressed when the dominant allele is not present.

• Dominant

• Recesssive

• Heterozygous

• Homozygous

Heterozygous phenotype is somewhere between two homozygous phenotypes, neither is dominant or recessive.

• Incomplete Dominance

• Co-dominance

• Linked Genes

• Multiple Alleles

Both traits are fully or separately expressed.

• Incomplete Dominance

• Co-dominance

• Linked genes

• Multiple Alleles
