When a homozygous tall plant is crossed with a homozygous dwarf plant,what is the percentage of dwarf progeny obtained in the $F_1$ generation by Mendel (in $\%$)?

The genotype of a plant showing a dominant phenotype can be determined by:

Mendel obtained recessive character in $F_{2}$ by ...$A$... the ...$B$... plants. Here $A$ and $B$ refer to

The method used to determine whether an individual is homozygous or heterozygous is known as:
