- Segregation for petal colour and gender in two families of backcross seedlings of (A. eriantha x A. chinensis var. chinensis) x A. chinensis var. chinensis (families 1 and 2), and two families of backcross seedlings of (A. chinensis var. chinensis x A. eriantha) x A. chinensis var. chinensis (families 3 and 4). The ratio of red to white petal colour of approximately 1:1 suggests that in petals of these hybrid families colour inheritance is a monogenic dominant trait.
