Which among the following characters selected by Mendel in a pea plant is a recessive character?

$A$: Dominance is not an autonomous feature of a gene.
$R$: It depends as much on the gene product and the production of a particular phenotype from this product.

Which of the following traits was dominant in the garden pea studied by Mendel?

The genotype of an $Rh^+$ individual can be:

In Mendel's hybridization experiments,what is a pair of contrasting traits called?

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: In an experiment, Mendel observed that the $F1$ progeny plants are all tall and none are dwarf.
Reason $R$: Stem height is a contrasting trait, with tall being dominant and dwarf being recessive.
In the light of the above statements, choose the most appropriate answer from the options given below:
