Detailed explanation-1: -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-2: -Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Detailed explanation-3: -The combination of alleles that an organism carries constitutes its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous.
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: -(JEE-noh-tipe) At its broadest level, genotype includes the entire genetic constitution of an individual. It is often applied more narrowly to the set of alleles present at one or more specific loci.
