An organism's genotype refers to the set of alleles it has for a particular trait. Alleles are alternate forms of a gene that determine specific variations of that trait. To determine an organism's genotype, you need to identify the specific alleles present for that trait.
For example, let's consider a trait like eye color. There are different alleles for eye color, such as brown and blue. An organism's genotype for eye color could be homozygous dominant (BB), meaning it has two copies of the dominant allele (brown) and expresses the trait as brown eyes. Alternatively, the genotype could be homozygous recessive (bb), meaning it has two copies of the recessive allele (blue) and expresses the trait as blue eyes.
In summary, an organism's genotype is the specific combination of alleles it possesses for a trait, which determine the expression of that trait.
