Step 1I'll solve this problem step by step, using the specified formatting guidelines:
Step 2: Define the Allele Combinations
- $$aa$$: Homozygous recessive
Let's analyze each possible genotype: - Both alleles are dominant - Will always express the dominant trait - One dominant and one recessive allele - Will express the dominant trait - Carries a recessive allele that can be passed to offspring - Both alleles are recessive - Will only express the recessive trait
Final Answer
- AA: Homozygous dominant - Aa: Heterozygous - aa: Homozygous recessive
