WebProtoplasts of sexually incompatible species have been fused and in some combinations have given rise to somatic hybrid plants. Partial elimination of parental chromosomes from either species is common in such hybrids, but total chromosome loss has generally occurred only with phylogenetically unrelated pairings. WebCompromised cytoplasmic segregation in emulsionmutants causes defective cellularization and developmental arrest of most progeny of mutant females (Dosch et al., 2004).
