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: -Offspring who have different alleles of a gene are described as heterozygous whereas those that have genotypes made of the same alleles (i.e. of a gene for a particular trait) are described as homozygous.
Detailed explanation-3: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.
