The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.

A plant with dark-purple flowers and a plant with white flowers are crossed. All of the offspring have lavender flowers. The all
dimaraw [331]
I believe the answer is incomplete dominance. Incomplete dominance creates a mix of the two phenotype(white and dark purple flowers) to create a third phenotype (lavender). Lavender is a mix.

Whereas, co-dominance would not be a mix but both traits would exist within the organism. In your question, it would be codominance if the dark purple flower and the white flower created a flower with white and dark flower pedals. This would not be a mix of the phenotype, but a co-existance of both phenotype.

I hope that helps! :D
