This is an experiment done by Carl Corren’s in which he crossed female flowers from GREEN, PALE, VAREIGATED BRANCHES with pollens obtained from GREEN, PALE, VAREIGATED branches in all combination as showed in picture below.

If you observe the progeny you can see the seeds from green branches always gave rise to green progeny, no matter whether the pollen was from a green, white, or variegated branch. Similarly, flowers on white branches always produced white progeny. Flowers on the variegated branches gave rise to green, white, and variegated progeny, in no particular ratio.Crosses demonstrated cytoplasmic inheritance/ mitochondrial DNA Inheritance of variegation in the four-o’clocks. The phenotypes of the offspring were determined entirely by the maternal parent, never by the paternal parent (the source of the pollen).

Innermost circle is female parent when crossed with pollen in middle circle and you get offsprings in outermost circle. Offsprings colour depends on female parent entirely.


I hope you understood!!!

This question is of cytoplasmic inheritance so just by seeing the offspring and female parent will be same..
