Multiple Choice 1 point Determine the following genotype as heterozygous or homozygous. aa Heterozygous Homozygous

## Step 1<br />In genetics, the term "genotype" refers to the genetic makeup of an organism. This genetic makeup is determined by the specific alleles that an organism possesses. <br /><br />## Step 2<br />When an organism has two identical alleles for a particular trait, it is said to be homozygous for that trait. This means that both alleles are the same. For example, if an organism has two copies of the allele 'a', it is homozygous for that trait.<br /><br />## Step 3<br />On the other hand, if an organism has two different alleles for a trait, it is said to be heterozygous for that trait. This means that the alleles are different. For example, if an organism has one allele 'a' and one allele 'A', it is heterozygous for that trait.<br /><br />## Step 4<br />In the given problem, the genotype is 'aa'. This means that the organism has two identical alleles for a trait, which makes it homozygous.
