Detailed explanation-1: -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-2: -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-3: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene.
Detailed explanation-4: -A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci.
Detailed explanation-5: -An individual that contains two different alleles of a gene is heterozygous.
