Plants produced through vegetative propagation are called clones. True False 2. is the vital link that ensures continuity between one generation to the next. 3. There are various types of reproduction. The type of reproduction adopted by an organism depends on the habitat and morphology of the organism morphology and physiology of the organism morphology of the organism the organism’s habitat, physiology, and genetic makeup 4. Offspring formed by sexual reproduction exhibit more variation than those formed by Asexual reproduction because- greater amount of DNA is involved in sexual reproduction. genetic material comes from parents of two different species sexual reproduction is a lengthy process gametes of parents have qualitatively different genetic composition 5. Vegetative reproduction in plants is a method of reproduction. 6.
