Detailed explanation-1: -In one sense, the term “genotype”-like the term “genome”-refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.
Detailed explanation-2: -In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
Detailed explanation-3: -The genotype identifies the alleles related to a single trait (e.g. Aa), or to a number of traits (e.g. Aa Bb cc). The term can be extended to refer to the entire set of genes of an organism (or a taxon).
Detailed explanation-4: -Genotype refers to the genetic constitution of living organisms. A genotype is the total sum of genes transferred from parents to offspring. Alternatively, a genotype can also be defined as the complete set of heritable genes that can be transferred to the offsprings from its parents.
Detailed explanation-5: -The genotype which consist of only one type of allele is called Homozygous.
