● Based on these observations, Mendel proposed that something was being `color{violet}"stably passed down"`, unchanged, from parent to offspring through the gametes, `color{violet}"over successive generations"`.
● He called these things as `color{violet}"factors"` Nowadays, we call them as `color{violet}"genes"`.
● Genes, therefore, are the `color{violet}"units of inheritance"`.
● They contain the information that is required to `color{violet}"express a particular trait"`, in an organism.
● Genes which code for a `color{violet}"pair of contrasting traits"` are known as `color{violet}"alleles"`, i.e., they are slightly different forms of the same gene.
● If we use `color{violet}"alphabetical symbols"` for each gene, then the capital letter is used for the trait expressed at the `F_1` stage and the small alphabet for the other trait.
● For example, in case of the character of height, `color{violet}"T is used for the Tall"` trait and `color{violet}"t for the dwarf"`, and T and t are alleles of each other.
● Hence, in plants the pair of alleles for height would be `color{violet}"TT, Tt or tt"`.
