Homozygous genotype | A genotype in which both alleles are identical |
Heterozygous genotype | A genotype with two different alleles |
Dominant allele | An allele that will determine phenotype if just one is present in the genotype |
Recessive allele | An allele that will not determine the phenotype unless the genotype is homozygous in that allele |
