An organisms genotype is what is it an observable trait? Is it an allele That is expressed whenever it is present or is it a trait that is expressed in a HOMOZYGOUS individual and last is it the set of ALLELES an organism has for a trait
The third option is correct. An organism's genotype refers to the set of alleles it has for a particular trait. These alleles may not always be expressed in an observable trait, but they determine the organism's genetic makeup for that trait. The genotype of an individual can be homozygous (having two identical alleles) or heterozygous (having two different alleles) for a given trait.
