Detailed explanation-1: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.

Detailed explanation-2: -The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

Detailed explanation-3: -An organism with two different alleles for a specific trait is called heterozygous or hybrid. For example, if T is the dominant allele for a tall tea plant and t represents the allele for a short pea plant, then an organism with the Tt allele combination is heterozygous and will form a tall plea plant.

Detailed explanation-4: -If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.

Detailed explanation-5: -An individual that contains two different alleles of a gene is heterozygous.
