Heterozygous

Homozygous

The alles possesed by an organism

Testing a dominant phenotype to determine it is heterozygous or homozygous

Pairs of alleles that both affect phenotype when present in the heterozygous state

An allele that only has an effect on the phenotype when present in the heterozygous state

An allele that has the same effect on the phenotype

The characteristics of an organism

The specific position of a gene on a homologous chromosome

An individual with one copy of a recessive allele, which can pasgenerationss it through generation

Having to identical alleles

Having two different alleles
