![Because apples are not true breeders when planted as seeds, propagation usually involves grafting of cuttings. The rootstock used for the bottom of the graft can be selected to produce trees of a large variety of sizes, as well as changing the winter hardiness, insect and disease resistance, and soil preference of the resulting tree. Dwarf rootstocks can be used to produce very small trees (less than 3.0 m or 10 ft high at maturity), which bear fruit many years earlier in their life cycle than full size trees, and are easier to harvest.[47]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:lijbb4mtq6gghmp2fvxgcp6g/bafkreia6pkj5qodtwsvhz5sdofsd7juycu3gam726a5wscj6kjhrle55ji)
![Many apples grow readily from seeds. However, apples must be propagated asexually to obtain cuttings with the characteristics of the parent. This is because seedling apples do not "breed true", instead they are "extreme heterozygotes", i.e. rather than resembling their parents, seedlings are all different from each other and from their parents.[45] Triploid cultivars have an additional reproductive barrier in that three sets of chromosomes cannot be divided evenly during meiosis, yielding unequal segregation of the chromosomes (aneuploids). Even in the case when a triploid plant can produce a seed (apples are an example), it occurs infrequently, and seedlings rarely survive.[46]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:lijbb4mtq6gghmp2fvxgcp6g/bafkreifn3er3kw5wldm6tf6wkrktttk5ichqs7lj7dwgqrl6tkuyvkxk64)
