show their effect with only one copy of the allele

Recessive Alleles

show their effect with two copies of the allele

Phenotype

“to show” physical traits

Genotype

“race, king” genetic makeup

Homozygous

organisms that have two identical alleles for a specific gene

Heterozygous

organisms that have two different alleles for the same gene
