Detailed explanation-1: -An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. 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.
Detailed explanation-2: -An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
Detailed explanation-3: -allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.
Detailed explanation-4: -A single allele means that there is only one variant of the gene. All alleles of the same gene exist at the same location, or locus, on a chromosome. Mendel states that a cell holds a gene containing two alleles, with one allele inherited from each parent.
Detailed explanation-5: -An allele is an alternative form of a gene. It is located in a specific location on a certain chromosome. The alleles are passed down from parents to the offspring through sexual reproduction.
