• It is included in cuatro O’clock bush (Mirabilis jalapa)
• You will find dark green leaved flowers and you will pale-green leaved vegetation.
• When the pollen of dark green leaved plant (male) is transferred to the stigma of pale green leaved plant (female) the pollen of pale green leaved plant is transferred to the stigma of dark green leaved plant, the F₁ generation of both the crosses is identical as per mendelian inheritance.
• In the reciprocal cross the F₁ plant differs from each other.
• The F₁ plant reveals the character of the plant.
• The fresh genetics is due to this new chloroplast gene found in the egg cell of one’s lady bush which adds this new cytoplasm while in the fertilization.
• The male gamete lead only the nucleus.
