How are alleles of particular gene differ from each other ? Explain its significance.
How are alleles of particular gene differ from each other ? Explain its significance.
Alleles of a particular gene differ from each other on the basis of certain changes (i.e., mutations) in the genetic material (segment of $DNA$ or $RNA$). Different alleles of a gene increases the variability or variation among the organisms. These variations are necessary for evolution and adaptations.

In a monohybrid cross of plants with red and white flowered plants, Mendel got only red flowered plants. On self-pollinating these $F_1$ plants got both red and white flowered plants in $3:1$ ratio.
