• It is utilized in 4 O’clock plant (Mirabilis jalapa)
• There are dark-green leaved herbs and you can pale-green leaved plant life.
• 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 new genetics comes from new chloroplast gene based in the egg cell of ladies plant hence contributes the fresh new cytoplasm throughout fertilization.
• A man gamete lead only the nucleus.
