Explanation:
Detailed explanation-1: -Genotype refers to an organisms genetic makeup, or genes. It is coded in DNA, and is often represented by two alleles (two letters, like AA or Aa). The combination of alleles (whether two dominant, two recessive, or one of each) is the genotype of an individual in reference to a particular characteristic.
Detailed explanation-2: -An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.
