Detailed explanation-1: -An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. 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-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: -Genes are chunks of DNA that contribute to particular traits or functions by coding for proteins that influence physiology. Alleles are different versions of a gene, which vary according to the nucleotide base present at a particular genome location. An individual’s combination of alleles is known as their genotype.
Detailed explanation-4: -Heterozygous Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent.
