Describe Mendel's Monohybrid experiment.

(N/A) Mendel's monohybrid experiment involves crossing two pea plants that differ in only one character (e.g.,height).
$1$. If we use alphabetical symbols for each gene,the capital letter is used for the trait expressed at the $F_{1}$ stage,and the small alphabet is used for the other trait.
$2$. For example,for the character of height,'$T$' is used for the 'Tall' trait and '$t$' for the 'dwarf' trait. '$T$' and '$t$' are alleles of each other.
$3$. In plants,the pair of alleles for height would be $TT$,$Tt$,or $tt$.
$4$. Mendel proposed that in a true-breeding tall or dwarf pea variety,the allelic pair of genes for height are identical or homozygous,$TT$ and $tt$ respectively.
$5$. $TT$ and $tt$ are called the genotype of the plant,while the descriptive terms 'tall' and 'dwarf' are the phenotypes.
$6$. As Mendel found the phenotype of the $F_{1}$ heterozygote $(Tt)$ to be exactly like the $TT$ parent in appearance,he proposed that in a pair of dissimilar factors,one dominates the other (as in the $F_{1}$ generation) and is called the dominant factor,while the other is the recessive factor.
