Which of the following represents a homozygous dominant genotype? (2021)

Step 1: Understand what a genotype is. A genotype is the genetic makeup of an individual, represented by letters.
Step 2: Know the meaning of 'homozygous'. Homozygous means that both alleles (gene versions) for a trait are the same.
Step 3: Learn about 'dominant' alleles. A dominant allele is one that will express its trait even if only one copy is present.
Step 4: Identify the letters used to represent alleles. Typically, uppercase letters represent dominant alleles, while lowercase letters represent recessive alleles.
Step 5: Recognize that 'AA' means both alleles are the same and both are dominant. This is what we call homozygous dominant.
Step 6: Conclude that 'AA' is the correct representation of a homozygous dominant genotype.
