• It’s found in cuatro O’clock plant (Mirabilis jalapa)
• You’ll find dark green leaved plant life and you may pale green leaved herbs.
• 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 heredity is due to the new chloroplast gene based in the ovum of your females bush and that contributes the fresh new cytoplasm through the fertilization.
• The male gamete lead only the nucleus.
