 We said earlier that replication would imply a heritability of exactly 1 in the absence of environmental variation. Although this is correct, the reverse is not true. In fact, take again a similar population as in  Figure 3(a),  but this time assume a different pattern of inheritance for the two types of entities, as displayed in  Figure 3(b).  With this pattern of inheritance, although there is no replication, entities on average have the exact same character value as their parent. In the case of the entities of size \(\frac{3}{4}\), some offspring have the exact same character as their parent, but that is not required either, as is the case with the entities of size 1, of which none of the offspring has the same character as their parent.
