1. How To Make A Fertile Polyploid Hybrid ... Some seedless fruits come from sterile triploid plants, with three sets of chromosomes rather than two. The triploid seeds are obtained by crossing a fertile tetraploid (4n) plant with a diploid (2n) plant.

Clarkia delicata (B) is a fertile tetraploid (4n) hybrid between C. epilobioides (A) and C. unguiculata (C). The diploid (2n) hybrid between these two species is sterile because the nine C. epilobioides chromosomes and the nine C. unguiculata chromosomes are not truly homologous;
