Detailed explanation-1: -Every trait has two alleles in each person. Humans are diploid because they have two alleles at each genetic locus. Although a gene may have multiple alleles, a person can only carry two of them.

Detailed explanation-2: -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-3: -Homozygous: Having two identical alleles for a trait.

Detailed explanation-4: -Gregor Mendel suggested that each gene would have only two alleles. Alleles are described as a variant of a gene that exists in two or more forms. Each gene is inherited in two alleles, i.e., one from each parent. Thus, this means there would also be having two different alleles for a trait.

Detailed explanation-5: -Multiple alleles exist at the population level and an individual can have only two alleles for the given gene. An individual can have only one type of allele (homozygous) or two different alleles (heterozygous).
