Mendel cross tall and dwarf plant. In $F_{2}$-generation the observed ratio was $3: 1$ (tall: short). From this result, he deduced
$I.$ law of dominance
$II.$ law of independent assortment
$III.$ law of segregation
$IV.$ incomplete dominance

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. Explain the basis of using $RR$ and $rr$ symbols to represent the geno type of plants of parental generation.
