Difference Between Gene and Allele

Genes are part of DNA . On the other hand, alleles refer to different versions of the same gene. There are other, more subtle differences between the two, which we’ll explore on this page: Gene and Allele

Chromosomal Changes

  • Genes are the different parts of DNA that determine the genetic traits a person will have . Alleles are different sequences on DNA – they determine a single characteristic of an individual.
  • Another important difference between the two is that alleles come in pairs. They are also divided into recessive and dominant categories. Gene don’t have any such differentiation. Gene and Allele
  • An interesting difference between alleles and genes is that alleles produce opposite phenotypes, which are contrasting in nature. When two partners of a gene are homogenous in nature, they are called homozygous. However, if the pair consists of different alleles, they are called heterozygotes. In heterozygous alleles, the dominant allele gains expression. Gene and Allele
  • The dominance of the gene depends on whether AA and Aa have similar phenotypes. It is easier to find dominators because they express better when they are paired with alleles.
  • Alleles are basically different types of the same gene. Let’s explain it to you this way – if your eye color is determined by one gene, then blue will be carried by one allele and color by another allele. Charming, isn’t it? Gene and Allele
  • All of us inherit a pair of genes from our parents. These genes are identical to each other. So what causes the differences between individuals? This is the result of alleles.
  • In the case of features, the difference between the two becomes even more pronounced. Trait refers to what you see, so it is the physical expression of the gene itself. Alleles determine the different versions of a gene we see. A gene is like a machine put together. However, how it works depends on the allele. Gene and Allele

Alleles and genes play an important role in the development of life forms. Of course, the differences are most stark in humans! So the next time you see all the hair and eye colors around, take a moment to appreciate the amazing power of genes and alleles!

    Summary: Gene and Allele

    1. Genes are what we inherit from our parents – alleles determine how they are expressed in an individual.
    2. Alleles come in pairs, but genes have no such pairing.
    A pair of alleles produce opposite phenotypes. No such generalization can be assigned to a gene.
    Alleles determine the traits we inherit. Gene and Allele
    The genes we inherit are the same for all people. However, these manifestations themselves are actually determined by alleles!
