Detailed explanation-1: -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-2: -Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.

Detailed explanation-3: -Gene is defined as a section of DNA that encodes for a certain trait. An allele is defined as a variant form of a gene. It determines an organism’s genotype. It determines an organism’s phenotype.

Detailed explanation-4: -Well, alleles are matching genes; one from our biological mother, one from our biological father. We have two copies of every gene (strings of code that drive some biological function on our chromosomes). They can be identical, but they can often have slight differences.

Detailed explanation-5: -So, basically nucleus of the cell contains DNA that is genetic material and gene is the portion of DNA. The pea plant has different traits like if we talk about size of the plant then it can be short and tall. So, each trait has a different forms and these forms are known as ‘Alleles’.
