• Characteristics

If a trait is homozygous the letters are the 

• Same
• Different

If you are homozygous recessive, the genotype would be 

• AA
• aa
• Aa

If you are homozygous dominant, the genotype would be 

• AA
• aa
• Aa

If a trait is heterozygous, the letters (alleles)are 

• The same 
• Different

If you are heterozygous, your genotype would be

• AA
• aa
• Aa
