Which one of the following can be explained on the basis of Mendel's Law of Dominance?
$A$. Out of one pair of factors one is dominant and the other is recessive.
$B$. Alleles do not show any expression and both the characters appear as such in $F_2$ generation.
$C$. Factors occur in pairs in normal diploid plants.
$D$. The discrete unit controlling a particular character is called factor.
$E$. The expression of only one of the parental characters is found in a monohybrid cross.
Choose the correct answer from the options given below:
Cross between the pure tall plant from $F_1$ and dwarf plant will give
Mendel obtained recessive character in $F_{2}$ by ...$A$... the ...$B$... plants. Here $A$ and $B$ refers to
A cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings ?
$A$ : Mendel gave postulates like "principles of segregation and principles of independent assortment" after studying seven pairs of contrasting traits in garden pea.
$R$ : He was lucky in selecting seven characters in pea that were located on seven different chromosomes
