Genotype is a term used to describe an individual’s genetic makeup, specifically the specific alleles that are present at a particular gene locus. The genotype AA refers to an individual who has two copies of the A allele at a particular gene locus. Here are six things you should know about people with genotype AA:
. According to healthline. People with genotype AA may be at an increased risk for certain health conditions. For example, individuals with genotype AA may be more susceptible to certain types of anemia, such as sickle cell anemia or thalassemia, due to the presence of the A allele.
2. Genotype AA does not always result in the expression of a specific trait. The expression of a trait is determined by both the genotype and the environment. For example, if an individual with genotype AA is born in a region with a high prevalence of malaria, they may be more likely to express the trait of resistance to malaria due to the presence of the A allele.
