Heterozygous

• 2 different alleles in a person's genotype

• 2 different alleles in a person's phenotype

• 2 of the same alleles in a person's genotype

• 2 of the same alleles in a person's phenotype

The difference between phenotype and genotype is:

• Genotype is the physical presentation of a gene while phenotype is the actual genes themselves

• Phenotype is the physical presentation of a gene while genotype is the actual genes themselves

• Phenotype is when you have 2 recessive genes

• Phenotype is when you have 2 dominant genes
