उत्तर
Monohybrid cross: It is a cross where two forms of a single trait are crossed or hybridized.
Mendel performed this experiment on the pea plant. He crossed the true-breeding forms of tall and dwarf plants and obtained the hybrid progeny. This is called as first generation (F1) offspring plant to self-pollinate and produced the second generation (F2).
