  • C. North
Part of the Science in Horticulture Series book series (SCHSA)


We have seen in Chapter 1 that with a knowledge of the mendelian principle of units of inheritance and a chequerboard diagram it is possible to work out expected segregations. The technique can be used by the breeder to forecast the numbers of individuals of different types in a family from a deliberate cross and also, in the reverse way, by observing the numbers segregating, to form an opinion on the gene or genes governing the inheritance of the factor or factors of interest. In this chapter we shall expand on what was described earlier.
