Define the following terms: $Genes$ and $Alleles$.

(N/A) $Genes$ are the fundamental units of inheritance. They consist of specific segments of $DNA$ that contain the genetic information required to express a particular trait in an organism.
$Alleles$ are slightly different forms of the same gene. They arise due to mutations and are responsible for the variations in a specific trait,such as tall or dwarf height in pea plants.
