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.

If two opposite alleles come together,one finding morphological expression masking the other,the fact is described as the law of:

The genotype of an individual is $RrBb$. How many different types of gametes will it produce based on the law of independent assortment?

The Law of Segregation is universally applicable because the gametes:
