Allele
The version of the gene. Different alleles can have different traits.
Genotype

Dominant Allele
The version of the gene that is more influential. The trait of this allele that will be seen over the recessive allele.
Recessive Allele
The version of the gene that is more influential. The trait for this allele will be hidden by the dominant allele.
Phenotype

Homozygous
A genotype with 2 identical alleles. It may be 2 dominant or recessive alleles.
Heterozygous
A genotype with one dominant allele and one recessive allele.
